Hi eerola,

Thank you for the response.

The AC compressor works correctly and the system is charged. The real problem is the CCU will no longer control the vents or the fan.

The moment I put the key in and turn the ignition the fan starts up even if the CCU is off. The fan only runs at one speed, full, and 80% of the air is going through the defroster vents with heat. So I get 80% heat in the defroster vents and 20% AC in the dash vents.

Any ideas?

Thanks again,
