Wow... just WOW... The guys at the shop couldn't figure out what is causing my A/C to lose its coldness. They kept hinting on the cycling switch and replaced it three times, but the A/C still continues to die after 2 hours. I kept mentioning that the evaporator may be clogged, but they assured me they ran water through it and it came out the bottom, how this is possible I'm not too sure of because I thought it's a 'closed' system.
I assume they don't have the proper technical experience, at least they fixed my thermostat cable, but the heater doesn't seem to be working. They said they would have to open up the entire dashboard and clean the whole system, which is a 2-day process and will set me back around $200. Regarding the A/C, they said I should take it to the dealership (DREAD) and let the men in suits have a look at it.
I'll list the issues and symptoms one more time here for anyone suffering from the same problems:
1. A/C runs ICE cold for around 2 hours, perfectly, the way it should
2. Noticeable increase in air temperature and humidity after 2 hours of driving (regardless of highway or city)
3. Also, the car does not 'sweat' after the 2 hours. I don't see any water dripping from the passenger side (I assume something must be clogging it)
4. Fan power also decreases drastically
5. Compressor cycles AND runs properly (I checked this myself)
6. AFTER engine shutdown, give it 40 minutes or so to find a vast amount of water dripping from the passenger side
7. Once water has finished dripping, the A/C will run properly for another 2 hours, and the circle of Hell repeats
As far as I can tell, it MUST be frosting up somewhere and for some reason which I nor that one garage can figure out. C'mon lads, anyone have any experience on this matter? 1ironwill? You seem to know what you're talking about?
