CAUTION!!! This may be a problem with the alternator and the charging. Blower fan will stop working if alternator is not charging. You may also see the battery light and brake light staying on as well! Advance Auto Parts or Auto-zone can test your alternator/battery.
2004 ford expedition front blower not working
Heater has just stoped working no power to control panel
First check the fuses. If they are good then check for power at the fan motor using a test light. If you have power, replace the motor. If not then check for power at the switch. If you have power coming in but not out, replace the switch. If power comes in and out, check the resistor in the air assembly. It will be close to the motor. It will have a plug with about four wires on it. If everything else checks out, that's probably your problem.
You can find detailed instructions on how to replace an door actuator and control valve on 2008 Pontiac g5 on youtube.com/watch?v=ttIZ_iCLFGo
it died
Solenoid valve on heating coil not opening or coil stopped up.
my heater switch on my vauxhall frontera as just stopped working but we can feel slightly heating coming through
heating element stopped working
heater core stopped up, heater control vavle not working, controls under dash not working, low in coolant, theromstant, radiator not flowing properly, water pump.
One of these things is the cause. Thermostat stuck open, replace it. Heater core stopped up, backflush the hearter core, and service the cooling system. Heater temperature control valve defective, replace it.
When the front blower for heat and a/c work fine and the rear does not on the 2001 GMC Yukon it could be a blown fuse. Automobile manufacturers rarely have both of these blowers running off the same fuse.
It is not your dash control,you will find that the problem is in the FAN RESISTOR LOCATED IN FRONT OF THE FAN HOUSEING UNDER THE HOOD.TO THE LEFT SIDE OF THE ENGINE
