My 1993 CSE A/C has been acting the same way for awhile. The fan also goes to hi and it blows hot air. When I check the compressor, the clutch is not engaged. I have a Seiko. I checked the pressures with gauges and also took it to an Indy and the pressures showed good. I couple of times I checked I thought they showed high. When the A/C is working it blows cold. I replaced the A/C relay as some people on the forum said that worked for them but mine still cuts out.

This winter the heater would stop blowing warm air after 15-20 minutes. I have the ACC set at 68*. If I increase the temperature it would blow hot air again at least for awhile. I replaced the cabin temperature sensor as the original is pretty old and it seemed the little fan was slow to spin up even after oiling.

I normally don't just change parts but these were easy to replace.

Interested to see what you what you find.
