Air Condioner Will NOT Turn OFF

[upenzi]

(1994 Infiniti Q45)

I was sitting in my car today picking my son up from school when all of a sudden my air conditioner (at the feet) turned on. The air conditioner was set to off and I hadn't even pushed the buttons. I turned it on and it blew through the vents like normal. But when I turned it off, the air continued to blow at my feet.

Does anyone know why this would be happening or how I can check the air system myself to turn it off? I'm afraid to drive it and I know the air being on is going to use all my gas.

Compressor only drags 3-4 HP, But yea you will use a little extra gas.

I think there might be someone else who currently has the same problem (*Silkysmothjud?).

But I would look in the service manual for the procedure that tests all the electrical components of the HVAC system.

Welcome to NICO.

If all else fails take your car to T3.

[upenzi]

Thanks. I'll take a look at the manual in the morning. Its at the bottom of my trunk lol.

What's T3?

[Infinitiguy19]

Your in Georgia an you haven't heard of T3 AKA Q45 heaven?

LOL! No, sure haven't. I just moved here from Cali a few months ago. This is the first problem ever with my car.

Thanks for the info. Checking it out now.

[upenzi]

OMG Paul, Thanks so much. This place is right down the street from me. Going in the morning. Will update when I return. Okay maybe not...open Monday - Friday.

Bro, I will almost bet that it's your blower motor resistor.

Check this info out.

[upenzi]

I'm a lady lol!! I took a look at that last night. I don't really know how to take off my glove box. But I'm gonna try tomorrow and see if I can at least see if its dirty or not.

If its dirty, what can I clean it with? Air Can?? Can I remove the sensor to make the air stop blowing?

2.) There are a couple of articles, look for one by elwesso. Might be in the Aritcle index in the sticky above.

3.) No.

.....Can I remove the sensor to make the air stop blowing?

Pull the blower fan fuse in the passenger compartment fuse box by your left knee.

My bad.

Are you talking about the air conditioner fuse? I didn't see anything on the fuse index that read 'blower fan'.

[goody90q45]

There's two 15 amp fuses in the right row labeled "Blower Motor". (Passenger compartment fuse box not engine compartment fuse box)

Okay...tried that. Didn't work. The air conditioner turned off but the fan at my feet continued. Opened the hood, and removed the blower fuse and BAM!!! No more fan blowing at my feet. I have no air conditioner right now but I can deal with it til I get the time to replace or have the air sensor checked.

Thanks everyone for your help!!! Every little bit helped. Much appreciated!!

I can't imagine how having no air is better than having non-stop air in ATL in the summertime - but as you said "I'm a lady" so your thermostat may be wired more like my wife's which includes taking a jacket everywhere, even in the summer, just in case a random snowstorm should hit Columbia, SC in August!

Anyhow, I echo Paul's suggestion about taking it to T3. They are a destination repair place for Q owners all over the country! We've had members drive 1000+ miles to have them take care of their Qs, so you're very fortunate to have them just down the road.

LOL!! Sounds crazy, I know. The plus is that I'm not usually in my car for long when I go places and I don't rely on the air conditioner for more then a few minutes when I am in the car. I usually just turn it on to cool the car upon first entry (especially with leather seats). After about 10 minutes we roll the windows down.

I'm still going to take it to T3. I'm just going to wait until I have the money to fix whatever the problem is.

Thanks

I guess I spoke way too soon. After taking out the fuse yesterday, the car started up perfectly with no air. Woke up this morning and tried to start the car, it shook for a few seconds like it started then it slowly cut off. Now it won't crank over. I put the fuse back and it still won't crank over and start.

Nothing was left on so I don't think it's the battery. But what do I know? I'm just a girl trying to make it with this headache of a car.

Any ideas on what could be the problem now?

[mtzgr777]

I'm not positive it's your battery since it started after you unplugged a fuse, but check your battery for corrosion or leakage of some sort....try brushing off the top of the battery near the solenoids.

Maybe try plugging the fuse back in and using a battery charger for a few hours?

I checked around the battery and it's clear. I put the fuse back earlier. It still won't turn over. AND the air didn't come back on either. I'm going to see about jump starting the battery later when my roommate returns. I'm stuck in the house

Could you explain what that means? Never have heard of a" clear battery."

[maxnix]

Compressor only drags 3-4 HP, But yea you will use a little extra gas.

Not at highway speeds where the increased drag will cancel the compressor running.

[upenzi]

Could you explain what that means? Never have heard of a" clear battery."

Clear as in Clean...not dirty...no corrosion or leakage.

[maxnix]

What about load test?

[upenzi]

What about load test?

what's that? and how do i do it?i'll try anything at this point.

Failure to attend Automotive Trade School for 2 years and receive a high GPA AS degree often leaves owners at tne mercy of trained expert technicans.'

Same with not having at least $500 or $5,000 or $15,000 in test equipment.Easier and less expensive to pay someone to rent theirs and their expertise.

If you can't help the problem...how about not saying anything at all. Thanks!

Depends how thirsty your horse is!

So think before you post next time, please.

[Q45tech]

Newies must be beaten into submission it is the American way. Why do you think the forum owes you anything? You owe us for free advice.

You must learn to take advice you think is painful or you get sent to the time out closet!

Amazing that someone BEGGING for free expert advice wants to set the standards in which they receive it!

The point is you must except advice or pay a technican to fix your problem or suck it up and learn to live with defects.

Free is never free, there is always a price to pay!

I really don't understand the attitude I am receiving from 'maxnix' & 'q45tech'. I came to this site recommended from another Infinity owner simply for advise on fixing my current situation.

I have been nothing but nice and very appreciative of all feedback received. I did not say the forum owes me anything at all.

This topic could have easily been bumped down the forum and never responded to. I appreciate those of you who have provided advise. Those of you who choose to turn this into something it clearly is not simply because you know more then me, are welcome not to respond.

Thank you

Infinity, eh?

I think you need to give more thought to your "current situation."
