Question the a/c on my 99' dodge ram 1500 works well for 5-10 minutes then goes hot. The blower still works, it just gets hot like theres no freon. I'll have to turn off the truck, let it sit a while start it back up and the a/c will work good again for 5-10 minutes and do the same thing.
Answer Hi Mike
You need to check system pressures when it starts to blow hot. It maybe that your expansion valve is not working properly. If your pressures are good while it is running good. Run system until it goes hot and check again it may show that your pressures on the suction side may have dropped below 5 psi. if so you need to change your expansion valve and drier
