#896 of 1037 1990 Acura Integra GS 1.8L
Sep 05, 2006 (10:07 pm)
I have a 90 Acura Integra and I am having some trouble with the A\C.
1) When I turn off the car the A\c fan stays on and runs down my battery. There is s sticker that says the fan may stay on for about 15 mins but it runs for longer than that. What can I do to fix this problem?
2)When I turn the A\C on while driving or parked my Temperature gauge goes into the RED. Also when it does that if I turn off the A\C the temperature gauge still goes into the red. What's funny is if it starts doing that while I have the A\C on and then I turn the a\c off it still goes into the RED once I stop. However, while it is going up(and I have stopped) and headed into the red with the a\c off I would excelorate while in neutral and the niddle would drop back too below half. Please help. Any help would be GREAT. Thanks in advance.
I cannot understand what is causing this because my friend's 1991 LS is doing the same thing.

Well, first off, that's not your A/C fan running when you shut off the car. That's the engine cooling fan. The reason it continues to run, probably, is because the car is running too hot.
There's something wrong with the cooling system. Could be the thermostat, the temp sensor, or the fan itself. I'm not well versed in your particular car, but I suspect the thermostat.

Thanks for your input qbrozen... Thing is on my friends 91 LS he removed the thermostat and it continued to do the same thing. So he then replaced it with a new one. Same problem continued. He changed the Coolant temp Sensor to the left side of the engine right under the distributor and two other sensors to the back of the engine(Not sure of their names, will find out)... but still he has the same problem...Any Ideas anyone... Thing is the temp niddle stays just below the middle all the time.. But once you turn the A/C/ on.. then the problem starts.

Does the A/C appear to work correctly?
If the AC compressor is failing it could be causing excessive load on the engine.
Is there someplace you could get your air conditioner diagnosed FOR FREE ?
One other thing what type of drving speed does it occur? idle, city , highway or doesn't matter.
I know you are new to Edmunds forums and that is why gbrozen and I tried to answer your question in this thread. However, this is the wrong place to post an Integra maintenace question and you would get better resilts if you post the same questions on the following thread;

I can't remember exactly on the 2nd-gen Integra, but many of the older Japanese cars had two electric cooling fans, one that runs off the temp sensor and a second one that runs all the time when the A/C is on. If that second fan has quit, the car will overheat all the time whenever you use the A/C, but will run without a problem the rest of the time. Might be worth checking.

I do have two cooling fans...Thing is they seem to work fine. The A\C fan comes on when I turn the a\c on yet the car will still show signs of overheat---on high way,city.. but even faster when I come to a stop in heavy trafic......
Oh by the way thanks for the help in moving my question to the correct place.. I am new to this and would take any help I can get....I just hope I am sending the message to the correct place this time.. If I am not...Mr. HOST please let me know what I should do .. Thanks again.

So you have personally witnessed both fans running at the same time with the A/C on? Then you have to go to the next obvious culprit - the radiator. Your car and your friend's are both old cars at this point - if these are original radiators, they may be so plugged up at this point that they are just barely doing the job most of the time. As soon as you put the extra load of the A/C on, they can't keep up with the extra heat generated, and you see rising temps and overheat as a result.
The radiators on the older Integras were always a bit of a weak link in the chain - you should make sure it is not leaking also. If it is leaking at all, it may not be maintaining the pressure necessary to do its job properly, or it may be low which would always cause problems only at peak times. And on a related note, the radiator cap may not be maintaining proper pressure if it is the original, which would also reduce the efficiency of the system enough to cause problems at times of heavy load (high-speed driving, running the A/C) only. You can pressure-test the radiator cap using a simple device available to the parts store, or a shop will do it for a few bucks I am sure.

I also have a '92 Integra and have this same problem. This has happened to me twice in the past week. I go to start the car, put it in drive and the S3 light flashes. The car drives like it is stuck in third gear and will not down shift or up shift. If I shut the car off and then restart, it is fine.
In addition the car has had problems starting on both days where the S3 light flashed. The car eventually starts after 15 - 20 minutes of trying. cars turns over fine but just wont fire. Local Acura dealer says they have never heard of this problem and can't diagnose unless they see it happen. I can't make it happen. It is random.
Does anyone know what causes this problem?
#905 of 1037 Help with 92 Integra LS
Sep 26, 2006 (10:10 am)
Need help. I have a 1992 Integra LS Automatic Trans. It stalls sometimes and will start up again after I turn the ignition. It stalls more often with the AC is on. I'm the original owner and dont' want to get rid of it. I brought it to the dealer and they can't find any problems with it since they can't replicate the problem. Help!
