In theory, indefinitely, however due to age and wearing of components, leaks can develop.Glad I found this thread! My AC is having similar issues and I just checked all the fuses.
I can hear the compressor click on and the rpms change when I push the button, so I'm starting to think I must be low on refrigerant.
By the way, how long should the refrigerant last on our cars?
HiThere is only 12V at C4 when the compressor relay closes, which is controlled by the ECU. Try jumping the relay contact by bridging brown/white wire to the red at the AC control module to see if the compressor starts.
If it does, it could be the Trinary switch not signalling the ECU to start the compressor due to low refrigerant level or defective wiring or switch.
The fans are also controlled by the ECU and run at half speed if the compressor is running.
Could be the resistor pack corroding.Guys, it just happen that while driving halfway i hear a 'tak' sound coming from the dash and my aircon stop working all together. no light, no air, no compressor.
I found out that my C1 fuse had blown, replaced that and all is working again.
Just want to know since nobody mention C1.
What cause C1 to fused??
I had a strange situation with this relay. My compressor stopped working. After checking fuses, I unplugged this relay and found it had been hot in the spot you can see in the picture. After cleaning it up and making sure the contact there would be good, I plugged it back in and the compressor cycles again. Weird. Hopefully, the issue does not return.The repair shop that I shall not name here tried to cook me!
Hooked up the connector and presto, cold air!
That means it leaked out somewhere. Time to start searching for a leak.My A/C suddenly quit working. The fan worked, the little blue dash light lit when pushed, but the compressor didn't engage. Checked LotusTalk of course for guidance (thanks everyone) and checked the usual things. The solution was to add some 134A to the system. As the freon was added, the compressor kicked on and we're back in business. Just wanted to thank all who have contributed to this thread.
