I had a new compressor installed. After the install, the check engine light came on. Then I ran the scanner and the following codes displayed. I don't know if I clear some of the codes, the remaining ones will clear. They are: P2600 (the voltage supply of circuit 87 has under voltage), P240C (the selector level position sent from control unit n1 5/5), P240C, B1062, and P2005-002 B11/4 coolant temperature sensor, short circuit to positive or open circuit (po117). Can not move the stick shift from park to reverse easily, B1062 the voltage supply of the sensors M1 2b1 and M1 2b2 has short circuit or Open circuit, M4/3 Engine/AC electric suction fan.

Hi,

Based on the location of the compressor, I suspect there has been damage to wiring or something disconnected.

To access the compressor, you need to remove the splash panel under the vehicle's engine compartment. Before doing that, check wiring around the alternator drive belt and in the engine compartment. If you find no issues, then you should remove the slash panel under the vehicle so you can inspect that area.

I attached a pic below showing the location of the compressor. Also, here is a link that you may find helpful when checking wiring.

Let me know what you find or if you have other questions.

Take care,

Joe
