Hello. I am glad I found this forum! I bought a '95 G20t with about 119k miles yesterday from a local trusted small dealer. Our '89 Corolla SR5 was getting up around 230,000 miles and it receently got stolen (recovered 4 days later), but we treated that as a cue to start our next chapter of car ownership. We were getting kind of tired putting kids in child seats in a 2-door anyway, and we realized the need for more security as well. The wife was really impressed with the G20t and I liked the styling as well, and they let us have it for 5 grand out-the-door so I thought what the heck! It has just about all the luxury stuff any average person would ask for, nice power, smooth shifting transmission (transmission was completely rebuilt a year ago and the dealer provided receipts for all work.) Power is not earth shaking but very good; I am doing 80 before I even realize it!
Only things that so far appear to be wrong:
(1) The cruise control does not work. The green light comes on in the cruise control switch when I turn the system on, but at freeway speed nothing happens when I push the SET button on the steering wheel. No CRUISE light, no response from the system.
(2) The security system doesn't arm when I lock the car. I tried all different kinds of things like locking with the little keychain transmitter, locking with key, etc. but the Security light doesn't come on for 30 seconds like the user manual says it should, and there is no response to "suspicious" activity to the car.
(3) Power antenna is bent. Can I just replace the antenna part or does the entire assembly (dealer said they run around $200) have to be changed? We have a Pick-A-Part in the area; can I grab one from a Maxima or something or is this antenna Infiniti specific?
I am wondering if a fuse or something stupidly simple could be responsible for (1) and (2) -- where is a good place to start my troubleshooting?
Also: Where is a good place to get more keychain transmitters or must they be purchased from the dealer, and how do they get "married" to the car?
Thanks very much in advance for any insight. I am planning to order a repair manual for the car but want to get a head start on the fixing of these minor problems to maximize enjoyment of my new sport toy!
New G20t owner; have a few tech questions

Hi,
Congrats on your G.
1) I would recommend getting a factory service manual for your car. It might have come with one. If not, check Ebay, it will guide you through obvious stuff to check on the cruise issue. Could be something as simple as the cable being disconnected. The throttle cable & cruise cable run in tandem at the throttle body. Follow the cruise cable to the vacuum pot that actuates it, see if it has any cracks or holes in the diaphragm. An FSM will assist you in how to test the individual components. Could be that the system isn't getting a speed signal from the trans. That could also be an easy fix.
2) Remove the door panels and look inside for a clear circular disc with a wire attached that should be located on the inside of the keyhole and has a switch in it inidicating the position of the tumbler. They have a habit of falling off inside the door of older G's. If the system doesn't know it's position, it wouldn't be able to arm. In other words, if it doesn't know that the door has been locked, it won't arm.
3) A take off junkyard antenna (from a G) would work short term, but wear items like that are better off purchased new & then one less thing to deal with again later. There might be a crossover application from another car, remove yours & go fish.
4) Transmitters can be purchased from Ebay also. Some of the other fellas are more knowledgeable about those than I.

Check your fuses first. The CC didn't work when I bought my truck...found out like 6 months later it was just a fuse.
You should be able fo buy just a mast for the antenna for around $20 maybe. It's a bit of work, but worth the savings.
HD is right, a manual is a good investment. Not a lot of G20 intimacy here unfortunately.

Why would fuses blow? Think study before you replace a fuse.......there is/was a serious problem somewhere.
In 11.5 years of Infiniti ownership never had but one fuse blow from a failed aux blower motor. Fuses are way over sized for circuits.
Unlike homes [circuit breakers] where multiple things get plugged in to same circuit.

As they said check all your fuses very common for the horn button/cruise button to short near the spiral cable blowing a fuse. make sure you check both the fuses in the car and under the hood. If those are all ok then you likely have a problem with a contact part of the ciruit typically the brake pedal switch or the set/cancel/resume button on the side of the horn pad. There is a proceedure for putting the system in test mode and watching the light on the dash to blink every time a button is activated. I will go through some of my training manuals today and see if I can find the proceedure to put it in that mode.

Pop you hood and locate the pin switch that gets pushed down by the hood when its closed. usually somewhere along the radiator support. it is an accordian rubber boot with a 2 wire gray connector plugged into it. Unplug it, lock all your doors with the remote and see if that light comes on solid for 30 secs. If it does your swith is bad you could either replace it or just leave it unplugged. If that doesnt work then you need to do as heavy said and get into the door and see if that lock cyl switch is stuck in the unlock position.

Yes you can just replace the mast. I would recommend you get the one for a G20 from a dealer. The mast likely is used on other model nissan /infiniti's but not sure which ones. there 3 or 4 different thickness masts available. Like Rob said they are only like 20 each new. Since yours is only bent and not broke you can just remove the old mast and feed the new one in without pulling the whole motor from the car. Remove the nut at the base of the mast on the body. You can use a pair of snap ring pliers in the 2 small holes on either side of the nut to loosen it. once the nuts off turn on your radio and the ant will feed out. make sure you get a hold of it before it comes all the way out so it doesent fall and scratch the car. Take your new one and feed the plastic cable down in the tube and have some one turn the radio off. bob the cable up and down in there while rotating it till it grabs it and pulls it in. if the motor stops be fore you can feed it all the way in just turn the radio on and off again rapidly so it will restart the motor.

Ebay probably a good source or the dealer. There is a procedure for programming them to the car in the maxima tech section its pretty straight forward I will see if I can get ya the link..
Congrats on your new ride.

heres the procedure for setting remotes.
http://www.nissaninfiniticlub....23955
Edit: I checked through the training manual and a couple different service manuals here at home. the procedure for doing this is not listed in any of it. As I recall this procedure is an off the record test procedure that was stumbled upon by some nissan techs some time ago and was never printed in any manual. I cant remember exactly how it was put in that mode but I THINK you push and hold the cancel switch while you turn on the main switch.If that is correct once its in that mode you release the cancel switch and start pushing cruise buttons, the brake pedal,clutch pedal if its a manual trans, and the cruise light will come on each time a switch is pushed. I will find out for sure on the procedure tomorrow from another tech on my crew whos been around nissan/datsun since the 70's. If he cant remember I can probably figure it out if I play with a car a little. Its easy to remember when its right in front of you.

Thanks much everyone! Lots of things here to get me started. I did check all the fuses and as Q45Tech predicted, nothing blown. I agree, the next step will be to get a factory manual for the vehicle and go from there. A diagnostic mode that tells what switches have been pushed would really be excellent. I'll try the sequence you mentioned and see what happens. Thanks for hunting that down! And thanks for the detailed info on replacing the antenna mast. Time to get to work! Take Care... Doug

Oops! Guess I got optimistic about the FSM too soon. Apparently the files comprising the online FSM have some sort of PDF password protected encryption. No mention on the "phatg20.net" site about that fact. Does anyone know how to unlock these files or must I purchase the rights to unlock them from somebody?

OK thanks for the setup detail on the FSM. Overlooked that little detail! Works now...
I got a couple things working. Still can't get the security system to work, but got the cruise to go. Turned out to be the cruise cancel switch at the brake pedal. (The one with the blue plug into the brown switch body.) From another forum I learned that the part number for this switch is 25300-62J00. I ordered that and the antenna mast from infinitiparts.com (cost: about $45 for both + DHL shipping) and they arrived in short order! I had to remove and disassemble the power antenna device since the plastic dealie from the broken antenna was stuck inside. It needed a little grease anyway! It now works fine. Almost there... just the security system and a scratchy sound in the right front speaker that I need to track down.
We took the car into the local mountains this weekend and I couldn't believe how great the handling is! Should be a fun ride.

Yep, checked the hood switch and seems to be okay. I started to go through the FSM procedure today, and changed the in-dash lamp while I was at it. (Now it flashes.) I was getting an abnormal reading on one of the door lock signals so I think it may be a problem like HeavyDuty was talking about (the little disc falling off the back of the lock cylinder.) Guess it's time to pull the door panels off... that should be fun! (!!NOT!!) I'll start with the trunk and then go to the driver's side door, as they are the most used.
