To clarify, do you mean the electric one in front of the condenser?

You probably want to look at this:

It looks different from some years of G50, as my '94 has a different air vent, but it's about the same either way.

Might be able to rebuild the motor, but it is probably better to replace it.

I don't about the 91 but I just removed one from a 95. You must remove the radiator and then the condenser to free the fan.

So you're parting out? You couldn't get a new rack?

no i'm not partin out the car...and what rack?i'm trying to remove the a/c condenser fan since it stopped working.

i found a thread where a member stated you can remove it from the bottom.

it's also said i will have to move the radiator and condenser out of the way.

which i don't mind...if the condenser hoses flex enough for me

My mistake. I must have mistaken you for another board member. I think he was also from Chicago. He had a bit of a scrape with his car and needed a new steering rack. I thought your post was about removing the part to ship to someone.

Sorry.

If I recall you should be able to move the condenser enough to get the fan out...

okay got it out!

i'm baffeled though cause the other day it was fine...no sqeeling, no struggle to turn on.

got the new one in.now the compressor was on. the fan was on.i had it all the way down to 65* on the temp cont.but the air was'nt cold.refrigerant level was good.

i'm assuming becuase it was 58*F outside is the reason the a/c wasnt cold like 3 days ago.thats normal right?

well i'm happy to report there's no leaks...which was my main worry.so it turned out the adaptor was the problem with the leak.

and the a/c starts out ICE cold then gets hot.you can see the refrigerant and what looks to be bubbles...

okay the condeser itself was leaking.

now the air still gets cold then it gets room temp.the condeser fan is smaller than the oem could that be the reason why??

Glad you had the non leak issue settled. Why do you think there are bubbles?

How can that be?

Did you read the FSM?

Take it to an exclusively automotive AC specialist. He can find the leak. Get a dryer and what ever other parts you need from Joe. Be sure to have the information form the manual for the amount of R12 and the correct lubrication the AC technician needs to replace after a complete (at least 1 hr.) evacuation of the system.

i found the leak.it was the condenser.

now my issue is the a/c gets cold for a split second then gets room tempurature.

if you shut off the car for about a minute then restart it and turn the a/c on. same thing gets cold then hot.

the bubbles were due to the fact the refrigerant was low thats all.

then i had posted that the fan i had bought was smaller than oem.could that be one of the problems?

but here's another update: i remember that when the condenser fan was'nt on a minute or two later the compressor would start sounding noisy.

Its hot, its humid, it is the middle of summer......end the misery and take it to a air conditioning specialist shop in your area for a professional diagnosis.....then make an intelligent decision to repair it yourself or let the pro do it. Guessing wastes time and usually is way more expensive than investing in professional diagnosis.

YOU started this thread OVER 90 days ago......how much more are you willing to tolerate??? Time to seek professional help!!!!!
