E34 Aircon Woes

[ehoe]

My E34 aircon recently seems to turn itself off intermittently then on again after a while. Whilst driving, you can suddenly feel the aircon is no longer cold and the aircon compressor is no longer running. After a while it will resume on its own and everything is back to normal. All the aircon lights and fan is still working and on when this happens. I know the aircon turns itself off as the idle RPM also drops abt 200 - 400rpm just like when you turn off the aircon manually. Anybody face this symtom before?. Any ideas whats the problem. Someone did ask me to check the aircon resister pack, does this have anything to do with the symtoms I have?. Any feedback appreciated. I guess time to go visit Naidu but just wanted some opinions in case someone else faced similar symtoms. Tks.

Go look for Naidu behind EPF. It is likely your alternator. Believe it or not..

Hmm how is the aircon and alternator related?. Care to explain if you don't mind, I'm curious to know. Hopefully it doesn't cost me a bomb to get it fixed. :-(

Take it to Naidu for diagnostics, he took 5 days to figure it out on my ex-car. It is related to the Voltage level.

i have this problem but a bit different....the air compressor shuts off and then on then off....if i turn the air cond off....wait a while then on again its fine....this happens usually when i first start the car... i noticed that if i start the car...wait a while then only turn on the air cond this does not happen...not sure as this in an intermitent prob...

I have problem on my E34 air-con last week till now, mine is cool is the morning and night, when in the hot sun it look like totally no ai-con at all but compressor is on, only in the highway it become better but no very cool.

Send to checking, the mechanic said have gas only the compressor is weak need high rev only have pressure to cool a bit. the mechanic ask me to change my compressure. Due to lack of time i didn't change it (need to go outstation).

May be need to send to Naidu to check up this week.

Any 1 face the same.

Didn't have time to go to Naidu's. In the end my car was due for its normal service so just asked my usual mechanic to have a quick check of the aircon since it was at his wshop anyways. He found the aircon temp sensor to be faulty so had that replaced and so far aircon seems to be ok. So didn't need to go Naidu in the end.
