After I replaced my radiator, my a.c.quit

Asked by Aug 23, 2016 at 09:30 AM about the 1998 Dodge Ram 1500 2 Dr Laramie SLT 4WD Standard Cab SB

Question type: Maintenance & Repair

I overheated the engine due to a slow leak, and
then drove the truck like that for two weeks until I
had both time and money to buy a new radiator,
refilling it before every trip.

After I replaced the radiator, I had transmission
trouble because the transmission cooling return
fitting was cracked. Fixed that, filed the
transmission fluid back up, and that's when I
noticed the truck getting hotter in the cab.

Engine cooling works well, and I have no further
transmission problems. But now the a.c. is kaput.
I've already been over the lines to see if we nicked
anything when we were doing the work, but it
doesn't look like it.

Anything I can check?

You have to hook up some A/C pressure gauges and add some dye to determine if you have a leak and or how much refrigerant is in the system.

Check the operation of the cooling fan or fans as well. (http://www.aa1car.com/library/cooling_fan_relay_problems.htm) I believe you have a secondary fan just for the AC condenser, so check the fan relay for that fan. The AC only comes on when both radiator and condenser fans come on.
