The heater motor in my truck only works sometimes and a lot of the time when it doesn't if you smack the heater box under the dash on the passenger side it will come back on, sometimes when it comes back on the motor doesn't run as fast as it should. It always gives the most trouble when the weather is cold outside, in the summer it does not do it as often with the AC
Hello Osbourne,
heater or 'blower motor's are prone to bearing failure,which can cause interference between fan & heater box;stopping,or slowing fan.consult a shop manual to DIY,or have a mechanic check blower motor .[I have found a stockpile of acorns causing a problem a time or two!!] Hmmm,Summer OK;Winter.........O nuts.......good luck!
SOURCE: A/C and Heat Driver Side Intermittent Problem
You will need to replace your driver side temp actuator. It is most likely sticking or over travelling. It is located under the dash directly below the a/c control head. It is bolted to the a/c box upside down with two small bolts. Let me know if i can help more.
SOURCE: heater blower motor works intermittently
I would replace the blower motor, this sounds like a motor brush problem inside the motor itself.
SOURCE: Cold AC but weak Airflow---Also Driver side not as cold as passenger
The air doors are controlled by actuators that on of them or so may need replacing.
SOURCE: blower motor does not work
I had the same problem, replace, replace, replace. Check, check and recheck. What I found was the blower motor resistor, located in the blower squirrel cage area, two prongs and a curly wire, was bad. Took the new one back, (it ohmed out okay, continuity ok, all ok!) replaced it with another, and Bingo, problem solved. Frustrating to say the least. After two relays and a blower switch, and test, test and retest. It was a faulty resistor. Made in Mexico. And no guarentee, even though new, it works. Trial and error. Even the dealer parts are Honcho en Mexico. Thanks NAFTA. You gonna make us all welfare babies.
SOURCE: Heater Blower won't work
Find the blower motor on the passenger side just above where the passengers feet would be. You may need to remove a panel (fairly easy). You will see a round metal housing about 4" in diameter. Turn on the ignition key and blower motor. Then tap the housing with a small hammer or a screwdriver. If the blower comes on.....replace the motor. If not, find the wires leading to that motor, undo the connector and check for power and ground in them.(You did check fuses first...right?)
