I have a 2005Chrysler minivan front heat does not blow back heat blows cold cold air front doesn't blow at all what could this be


If the front heater does not blow any air suspect a defective fan motor or resistor. You can try turning the blower on and banging the underside of the passenger dash to see if it begins working again. If it does, suspect a bad fan motor. If blowing only cold air, the most common problem is a low coolant level

Heat don't work Just blows cold air but the control for the heat is warm to touch


Check coolant level. Start cold with cap off and add coolant as necessary with HEATER ON, while running. Let it get up to operating temperature and rad fan comes on 2 or 3 times, then make sure topped up and put cap back on.

2005 GMC Sierra 1500 - heater blows, but only cold air


Check coolant level. Check for heat at the heater hose going from water pump to heater core at firewall. Check to see that cable is moving coolant control valve from the closed to open position. Low mileage so it shouldn't be plugged heater core.

Would the heater control valve malfunctioning make the engine overheat blowing hot air out the heater one moment,then not blowing the hot air, temp gage spikes 225 plus. The motor takes awhile to heat up...


Heater control valve malfunction will not cause engine to overheat unless coolant is leaking externally...Overheating going down the road can be the result of a few different things...Partly clogged radiator...Insufficient air flow due to possible fan problem...External coolant leak...Make sure fans are operting properly and have cooling system pressure tested for leaks...Gaining and losing heat on the inside of the vehicle usually means system is low on coolant but you must find out where coolant is going

'96 Beretta has no heat. Coolant level okay. Fan


when you start the car and let it warm up, does it reach normal operating temp.? Does the needle stay in the middle? If not, it's time to replace the thermostat. If it's ok, then your blend door is stuck or broken and may need replacement or repair. when you move the control to hot or cold, the blend door opens accordingly allowing cold hor hot air in.

Heater 1998 chevy s10


You need to check your coolant level first. If it is low you have a coolant leak. No hot coolant=No heat

1998 S10 heat wont work sometimes


When you say the heat doesn't work are you meaning the fan doesn't blow out hot air or just doesn't blow out any air? if it blows cold air sometimes when you have the heat on then it could be poor circulation through your radiator or a weak water pump. make sure your radiator is clean on the inside, not too corroded or nasty inside. You can buy a radiator flush thing from wal-mart or any auto parts store. See if it helps.

Heat works on driver side, passenger side blows cold air.


Did you check your coolant level or was it low and you added to it at some point? If so the system my need to be bleed or worst case the thermostat is going bad.

Heater blows cold air


I had the same problem with the heater only working when accellerating. Found the overflow tank pick up tube was kinked. This of course made my coolant level low. So when the cars hot the coolant would push into the overflow, but when the car cooled the kink would prevent it from flowing back to the radiator.
