Question about 2006 Chevrolet Malibu LT

1 Answer

Blower fan not working.

Currently, I'm not getting any heat in the car because there's no air coming through the vents. I know the radiator itself is fine because as I get going I can feel the heated air from the engine come through the vents. When I go to turn on the heat, however, nothing happens. Doesn't matter if it's on defrost, dash vent, high or low setting, nothing happens. This has been happening on and off for about a week, where the fan wouldn't work, and as I got going, the fan would suddenly kick on. Sometimes it kicked on again if I turned the car off and then back on. But, I haven't been able to get it to come back on for the past two days. I'm thinking the blower fan is shot.

Possible speed control is open circuit or the fan motor. Check you have supply to the switch/motor.

SOURCE: a/c blower issue. 2202 chevy trailblazer

your blower resistor bad or the blower motor control switch is bad. no air flow from top vent make sure vent open.because you can manual adjust them not to blow air on you.if all is have leaking vacuum hose or vacuum actuator.or air door stuck.the AC and HEATER control bad.its not allowing vacuum to open air door.

SOURCE: The fan/blower only works on the high setting.

It probably is the fan switch itself. They are around $30. for a new one. You can take it out and check to see if you have power to all the settings with a ohm meter or test light. They are not real hard to take out.

My windows are not defrosting properly.

Do you have heat? Does the fan turn on? are you getting air from the defroster vents close to the windshield? If you have heat make sure the defrost control is working. I'd open the outside air vent and turn the blower on high speed. If there is no heat, the heater control valve is not working. Double check the radiator fluid tank, make sure you have enough fluid (antifreeze) Low fluid levels can reduce the hot water flow to the heater coil inside the car. If there
is no air flow through the defroster vents you may have a problem with the fan control, or the fan motor. Good luck.

Blor fan is not working in my 1996 jeep cherokee

So you're getting heat, but the blower fan itself is not working (hot air comes from open vents, but not "forcefully blown in" from the fan? Were you hearing any squealing noises when the fan was on, before it quit working? If so, your fan motor is probably dead. It could also be the fan switch, or a fuse or relay. in the circuit.

My 99 chevrolet monte carlo z34 heat is not that hot and air works for defrost but not dash vents?

check radiator fluid level it take hot radiator fluid to pass through the heater core to produce the heat in your car VIA the fan. also check or replace your thermostat it could be bad and stuck in an open position thus radiator fluid not getting hot, no hot fluid no hot air
the other problem sounds like a duct hose under you dash has come loose locate and reattach.

2003 dodge durango front heater will not blow heat. but when driving heat will slowly come throught the heater vents. what should i check?

Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

A/C and Heater will not blow air..

Blower motor resistor is most common ($20-$70) it controls the blower motor fan and speeds or fan relay fuse (usually under the hood) If it's not either then the blower itself is bad. You can pull the motor and apply 12volts to it to test, if it spins then the resistor.
