I got 3 more cans of R134a, one with the UV dye in it and put 2.5 cans in the car. It has been running for almost an hour now and I cannot find a leak using the UV light. I think I found the expansion valve under the driver's side dash and it shows no signs of leaking....all under the hood looks good to....so the only place left is the evaporator....and it too cool here tonight to generate any condensation......
How hard is the Evaporator to replace?
Also I noticed that the door the opens behind the glove box that allow inside are to be recirculated, was not open...when does this open? I have the controls sent to "min" and the blower on high.
Also what should the PSI be on the high side when it is about 68 degrees outside.....
