The blower/fan is working. I am wondering if perhaps it is the thermostat. It may be my imagination but it seems the radiator top gets hot quickly. Is there any way to rule this out or to check for another problem?

You can check heater hoses going into heater core to see if they are both hot.

Possible AC ECU problem.

Hi again! Both hoses leading to the heater core are hot. I had previously run a diagnostic check in the garage. It initially showed code 21 (ECU?) And code 23. When I backed the car out into the sun, both the codes went away.

I took my Lexus to a small-time mechanic. He called me back to say the heater is working and that the compressor is bad on the a/c. I have trouble believing this since the clutch was working properly. Do you have any suggestions?

I had a friend check the pressure w/ gages. The low side is 70 to 75; the high side is 50. Therefore, the compressor is not compressing. However, the clutch is engaging, the belt is turning the compressor timely. Does this absolutely mean the compressor is bad. There are no squeals or drag on the belt. Note: I did have a mouse under my hood. Could it some wire problem? The a/c is blowing but not cool. If it is the compressor, would you recommend one from a salvage yard?

Those readings are funny. Will have to research more. Salvage compressor is fine if it's much reduced from new and if it is guaranteed to work.
