Cavalier has a 2.2 engine...trouble codes p0118 and p0530. When the engine is on the compressor seems to not move and the belt isn't on it either. Is that normal. A/c light turns on but turns off later on. And also the fan doesn't turn on at all. Relay is fine but I'm guessing the motor is done. Bought the connector for the pressure sensor on the a/c line....will this help? And also I'm installing a new ect sensor soon. Can any of these be the causes? Any help would be appreciated.

 

should i buy a new belt and apply it on the compressor?

 

update- installed the new connector just need to add refrigerant. hoping theres no leaks.

as for the heater and the ect, heater core is done and the ect isnt causing the problem. gonna check the wiring soon.

 

When you put in refrigerant, also put in UV dye and then you can check for leaks and easily see them with a black light

Hopefully this works out for you

 

Installed new fan motor and heater core today. Heat works now and so does the fan. Now moving towards the ect and the ac. Temp gauge in car doesnt work and i already installed a new ect. any help?
