A/C unit will kick on-off every 2seconds without cooling the truck, have checked the refrigerant and
appears full, suggestions?
by kickin on im assuming ur talkin about the clutch on the compressor, its supposed to do that even if ur truck had the a/c turned off to circulate the refridgerent, u could have a leak in the system thats the usual cause of "not cooling" try a quick seal kit and a couple cans of recharge, if that doesnt solve the issue, it will require further diag as to y the system is not operating
i would drain the system and then shot dye in the system and refill it and wait a week and get a black light and look and see if you have a leak
You might need a new ac compressor.
