Thank you. First check and see if the cooling fans are coming on when you start the engine and turn the AC on. Please let me know.
Customer: replied 9 months ago.
all its working except the clutch on the AC pump is not engaging, no current flowing to the clutch, all fuses are OK, what else could be wrong ?
Expert:  A. Penland replied 9 months ago.
The problem can be caused by several items. The AC compressor clutch relay in the engine bay fuse box, a cycle switch, wiring or the PCM (Engine Computer). It will require some testing that I can walk you through if you have a test light or digital multimeter.
