Re: AC not working: Climate Control Module?

You were getting 42F out of registers with the temp outside 100F?

That sounds too good......wonder if the evap was freezing up.....

You don't say what year the vehicle is....if you have a 3 wire pressure sensor in the system, it can't be jumped.......by jumping it, you make the PCM think the pressure is too high or too low....if the sensor is reading correctly, then you need to know if the PCM is getting a "request" from the A/C control head.....
