I have a 2004 GMC Duramax; It has heater and the ac problems. If the heater is on you cant shut it off and turn the ac on. And Vise versa but works once in a while. Or sometimes you have to shut the truck...

the actuator motor for the ac/heat door is broken. best bet is to unplug ac fuse in winter and disconnect heater hose in summer

2005 Chrysler Pacifica heater goes from hot to cold by itself.

Under the dash there are doors that open and close to give you hot or cold. Sounds like you have a vacuum leak in a hose or one of the vacuum motors that moves the door I would hook up a cheep hand held vacuum pump to each one and see if they hold vacuum also the one that opens the door that keeps the heat blowing is the one to look at if the door stays open and you have heat with the hand pump and you don.t have to keep pumping it the hose or farther back is leaking.

I have a 93 delta 88. heat comes and goes. we have changed the thermostat, and checked fluids. the car does not run hot. but the heat will work one day and blow cold the next.

Check the vacuum diaphragm in the heater hose. It's a little metal valve with a hose going to it. When the heat is turned on the vacuum line opens the valve letting hot water pass through the heater core.

When i turn my car from hot to cold or vise versa it sounds like something is disconnected to the flap.can i see a diagram of the flap?

There is a tsb about replacing the secondary heater door for that noise. The door warps and hits the main door. It can also cause the heat control to be inop.The dash has to be removed to replace the door.

Sounds as if there may be a vacuum leak somewhere, possibly behind dash causing it to switch back and forth from hot to cold and vise versa

2004 f-150 heat control will not switch from defrost to floor

You have a vacuum leak that is not only affecting motor operation but also the correct operation of the vacuum switch controlling your damper. Need to have that matter resolved -check all vacuum hoses and fittings for integrity/tightness. Vacuum switch itself might be leaking!
