Hoping for some direction
Start truck and I can leave it idling in driveway for 1/2 hour and the ac cycles normally , nice and cool, ac clutch cycles normally.
Start out and within 5 mins the ac stops functioning. clutch does not cycle.
Shut truck off and start the next day and the ac works at first, then drive for a couple of minutes it stops
I have replaced the low pressure/cycling switch and connector checked all fuses in the fuse relay under hood and interior fuses a well.
Any suggestions would be greatly appreciated.
Cooking in the North 91 degrees.

 

Have you checked the freon

 

Yes, before changing the cycling switch.
Now even when you bypass the switch it still does not engage. after vehicles has been moving.

Would it still function for a 1/2 hour without moving if the freon is low,?

Anything electrical that might be the cause? common wiring issue with this model?
