Tried to search but didn't find a match. I'm not sure I have only one problem .Hopefully I can provide enough information :
Ac does not blow as cold as it did 3 weeks ago. Gauges were showing H - 225 L 25-20 with ac clutch engaged . when it disengaged it dropped to H 150 then 125 and stayed at L 40 According to a chart I found those numbers were low . I put a can of 134 in .
After that I turned the engine of and restarted the car . Now we started at 40 low dropping to 35-30 and then 25 . High started at 225 and then 215 - 200 as it kept running . The ac clutch did not disengage at all.
The ambient temp was 94 and the temp coming from the vents was 85* . I also tried the blend door r-set as shown on Sparky's .
The supply line from the compressor is cool to the touch. Low pressure section of the line is also. Hp side of the line is hot . The Accumulator is also.
Yesterday we had slightly cooler air coming out of the vent , but at a stop sign it become warmer . No fan clutch. Two electric fans .
It has dual electronic temp control . all vent selection functions seem to work as the should . The catch is that the blower speed selections show on the readout as they should . The blower speed does not always . match the readout . It may be stuck on low . Drive a while turn engine off and the go again and it works as it should. As I have messed with it in the driveway it will sometimes correct itself if I mess with Auto select button.
Sorry to be so long but I wanted to give as much info as possible . I am stumped and wife is grouchy with no AC in 95* temps . I told her to toughen up ! Thank you for your help .
