What causes a heater head to fail on a car?

What causes a heater head to fail on a car?

It failed (ruptured diaphragm) and allowed oil to be sucked into the vacuum lines. This oil caused the switches/actuators inline to also fail. They also mentioned heater control head problems as a result, I believe (sorry, going from memory).

Why does my heater not change the temp?

The temp control switch is only switching temps half the time. Sometimes it will work sometimes it wont. I can turn it back and forth from hot to cold and it will not change the temp coming out of the vents. Its random, sometimes just playing with it for awhile will get it to work. Any idea what it could be? Hoping its just the switch.

What to do if your car heater is not working?

Open glove compartment, and lift tab in upper left corner to allow the glovebox to swing down completely towards the passenger floorboard. 3. Gently remove the line that enters the “Vac Unit”, and then the “Vac Unit” itself by wiggling it upwards off its mount. Once removed gently swing it towards the drivers side and out of your way.

Why do I get no heat from my air conditioner?

I get no heat all, i am assuming the switch works since if i have it on AC and use the temperature control the fan slows down when it hits 72 or whatever i have it set to, flipping it to heat the air temp is the same. Heading to advance auto shortly hopefully they have it in stock

Why is my Chevy 1500 heater not working?

When blower motor is on 2 highest settings,air can be heard roaring in the vent system but the proper amount of air volume coming from vents is not as when newer.Took door actuator off and seems to be working fine off of unit. Will explore the possibility of mode actuator being stuck or bad.The search for this problem continues.Post 5/26/2011.

Why does my AC quit blowing cold air?

Sometimes when driving down the road and I let down my window and then AC quits blowing out cold air; however, very hot air begins blowing out from underneath the steering wheel. When I let up the window the AC just blows out warm air out the vent and the hot air quits blowing out from under the steering wheel.
