Blowing hot air all the time

2000 chevy blazer that blows hot air no matter where climate controls are set . the air temperature coming through seems to run along with the engine temp , because the air gets hotter as the engine temps rise to operating levels even though climate control is off or turned to cold and the a/c is not turned on either

There is a door that opens to the heater core.When the vacum control in the dash gets old the diaphram gets to flimsy to close one port so it puts vacum to all ports.Therefore there is not enough pull to engage the vacum motor to move the trap door.Change the switch in the dash. Check to make sure that there isn't an obstructing object in front of the door before you buy a new switch

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

I have a 1993 dakota, the climate control only blows though the window area. I cannot get air flow to move from the window to any other setting, floor or dash. Wondering what the issue may be and how to...


wakow4u, What you have to do is look for a vacuum line that comes from the engine and enters the passenger compartment through the firewall. This vacuum line controls the climate control. A small rubber hose that fits tightly will suffice as a good and quick repair. Good luck with this.

On my 1995 chevy blazer s-10 my face vents are not blowing air


Your heater valve is stuck open, also in a pinch you can crimp off your hose to the heater coil at fire wall. Try to find the heater valve vacumb hose under the hood see if it is bad and fixit. or some models have a cable to the valve could be broken.
