AC Clutch

[yobie]

My ac clutch is not engaging and I do not have power to the clutch. There is no direct relay/fuses that I can find, but I have check all and all are in working order. I believe the PCM controls the ac?

I have tried to check/jump the low pressure switch (by my finger), but unable to since this is not getting power. Oddly enough I have power at the clip before the switch (circled). How can I lose it by the time it get to the switch?

I also think you lost the charge, picture show green on the dryer and to the right of it. Just put a gauge set on and see if you have any pressure. If you have a good charge then as stated , jump with jumper till you find the open.

Yes! There is a reason for the low pressure switch. Why do you want to bypass it? Have you checked for good grounds? DC power needs a place to go. Also, you are low on coolant.

Edit: On looking at your photo, . . . . again, I believe you are pointing to the high pressure switch.

Try a jumper wire from a known source of 12 volt power to the fan clutch. Then you just work your way backwards with the jumper until you find the place where the power stops.
