97 dodge dakota

Postby Tonylate » Tue Jul 26, 2016 2:31 pm

I have a 97 Dakota that the a/c won't cool down the cabin.
The pressure read in the normal range on both the high and low sides. The high side is hot the low side is cold all the way back to the firewall. Condensation is present on the tube to the firewall.
The compressor runs and cycles just fine.

It is as if the refrigerant has bypassed the cabin evaporator.
Any advice?
Thank you
Tonylate

Does your temperature door make noticeable movement sounds when you go from hot to cold to hot? with air blowing? try pinching off heater hose and see if that lets you know if temp door is in correct position...

If the suction tube is cold-cold and water drips from the drain, you have two possible problems: 1) a blender door or actuator malfunction, 2) a plugged evaporator. The first is far more likely.
