99 dodge ram 1500 trans/ac issue
07-08-2010, 09:21 PM
I have a 99 dodge 1500. The truck runs great when the ac switch is disconnected. When its connected and you turn on the ac it makes the truck run like crap. It makes the tps jump around like crazy. I have changed the tps, iac, map, ac switch etc. The even crazier thing is it runs worse on high cool and when its on just main vents. when its on main and feet it runs ok but still acts up. Anyone have any ideas? Could it be the blower motor resistor? Im stumped... Please help...

What does the voltmeter in the instrument panel do/show with the ac on max?

I have a 2001 that is doing the same thing, any luck figuring it out?
