OK, so we're in the middle of a heatwave and I don't think my A/C is doing a good enough job. Today when I was driving home it was 99 outside, and my car was probably a good 120 when I got in. I have a good 15 minute drive, and it was still friggin' hot in it when I got home. I found an excerpt from the shop manual about measuring the output temperature, so this is what I did, and the temperatures I recorded.
Outdoor air temperature during test: 99.1 *F
1. Put the car in Park, and turned the heat on to 90 *F for both sides, on highest blower setting, with recirculate on. I let that run for 5 minutes.
2. After the 5 minutes, I measured the cabin dry bulb. It was 134.3 *F
3. I put the A/C on 60 *F for both sides, highest blower setting, with recirculate on. I let that run for 5 minutes.
4. After that 5 minutes, I measured 99.4 *F cabin temperature. The passenger-side vent was blowing 91.9 *F air, and the driver-side was blowing 77.4 *F air.
According to what I read, I should have been seeing about 45 *F air coming from the driver-side vents. I know there is a 14.5 *F difference between driver-side and passenger-side output temperatures, but 77.4 is still much higher than 45 *F. I would think that with the output temperature being that far off, the charge would be low enough to cause a CEL, or blow a fuse, right?
Any ideas/help is greatly appreciated - it's hot a sh!t out right now.
