I have cold air one the drivers side and hot on the passenger side. Could my control switch be bad and not overiding the A/C switch when it is slid it should turns off heat?
Seems like a blend door is stuck half way. But you said they were working fine. Maybe check the cables if you have cables and make sure they haven't come loose.I have cold air one the drivers side and hot on the passenger side. Could my control switch be bad and not overiding the A/C switch when it is slid it should turns off heat?
Thanks I will take that advicevacuum test pumps are cheep and will test for operation and bleed down leaks.
To answer your question, you should be able to run both A/C & heat at the same time. That is how you dry out a foggy windshield on a 40 degree rainy day with 100% humidity. You dry the air first, then heat it.
I was going to ask if you are sure that the system is fully charged, but since you said cold & "hot" vs cold & warm, I would suspect an actuator vs low refrigerant.
I will check the water valve as suggested. That could be not opening/closing as it should.if it is factory ac , the valve on the fire wall is,,, not adjusted correct, or leaking internally, it is connected to the temp slide on the ac/heater controls.
It is designed to run the AC and heat at the same time. For the reason Ranger16 mentioned and also to increase the temp a bit if the AC is too cold. However, you should not have cold on the left and warm on the right. It all comes from the same source so the temp on the right and left should be equal. This is assuming you are running a stock system.
