The engine cooling fans turn on high about 10 seconds after starting my van. The a/c compressor clutch does not engage. I replaced the high pressure a/c switch thinking that the high pressures might be too high. No luck! Retrieved code P0532 the other day. Has anyone ever seen this problem before? Thanks.

 

Have you checked the charge of the AC system?...maybe you need to recharge with refrigerant or pressure is too high in the system? Both of those could set off that code as well as the sensor that you replaced being bad.

 

Will check the refrigerant level. Thanks for the reply
