90 reatta, service ac.is on and compresser clutch

Does the AC have a charge in it, that would be the common reason for no AC in this year. Temperature control module?? no such part.

If you turn the control on the dash to off and the compressor is still running, the relay is stuck or the clutch has failed to release.
You should be able to unplug the compressor clutch and stop it too.

code 022 TPS ( throttle position sensor ) signal high


code 041 camshaft sensor signal

The diagnostic port on the '88 Reatta is located under the driver side of the dash to the right of the steering column. Very cool car by the way.

Probably your security system:
PassKey I, and II
Similar to the VATS system, these vehicles also used a pellet key. You can identify this system by looking at the key. It has a black resistor pellet with a thin metal edge running along the key. The system enables the starter, but shuts down the injectors after initial startup. So the vehicle would start, then die. This system has a "relearn" feature. It was used on these vehicles
Buick
Riviera/Reatta 90-01

Is the security light coming on? Are you using the factory key with pellet inside? Do you have another factory key you can try?

This light indicates the AC compressor is turning off and on (cycling) to often in a set period of time, this is caused by a low system charge, you need to have your system checked for leaks and then topped off, in most cases the light comes on before the system stops cooling.
