Fans not turning on at all


Check fuse panel first for heater fan. If fuse is blown, there is a reason for it like motor has seized or has shorted out. If fuse isn't blown, it might just be a bad switch on the dashboard

Why does'nt my heater fan work?


There could be a number of reasons. Fan is bad, fan area in box is so clogged it doesn't allow fan to spin, a bad switch at instrument panel, a bad resistor, bad connections. I would start by removing the fan. I believe you will have to go in behind the glove box. Remove the fan and check to see if it works, it may be fine if bad replace. Check inside of box for leaves and any other kind of clutter that may be preventing fan from spinning. Check wires to fan for mouse damage. Mice can take there toll on a cars wiring. If all is well so far check the switch in your dash. Switches are funny, some last a life time some don't. I believe you will find your problem, following these steps. GOOD LUCK FRIEND.

How to remove and reinstall heater fan motor on a 2002 Buick LeSabre ?


remove the plastic panel underneath the passenger side dashboard area. This panel contains built-in retaining clips and simply pops off by hand.
remove three 8mm holding the blower motors assembly into the dashboard HVAC unit, use a 1/4-inch ratchet and an 8 mm socket. Remove the blower motor's electrical connector and discard the old blower motor. Install the new blower motor in the HVAC cavity and replace the 8 mm mounting nuts. Reconnect the blower motor's electrical connector and replace the plastic panel. Turn on the ignition and test the blower motor on all of the fan speed settings

I have a 1997 oldsmobile eighty-eight and the fan one day over the summer 2010 went off and on with the blower switched on. It caught my attention but kept my fingers crossed. Within a few days the fan...


It does sound like a bad switch --- possibly arcing and overheating -- or it could be dirty / corroded contacts on the switch or in the wiring harness connector.

The switch should come out fairly easily after getting access to the back of it -- it probably has tabs on it which when pressed in will allow the switch to come out the front.

P.S. The blower motor resistor would not cause an overheating switch -- a bad resistor would at worst allow maximum current to go through the switch -- the switch is designed to run the blower at full speed (maximum current) w/o overheating...

Heater blower stopped working, all the controls work and there is heat when i'm on the move but fan won't blow and then every so often it kicks in for a while....any help?


That's frustrating. If the fan motor sounds healthy when it does run the you probably have a faulty fan switch. When it does come on if it works at all speeds then it's possible there's a bad connection at the switch but this is unlikely. Unless you have experiance with replacing dashboard switches on a VW you wiil probably have to pay a tech to replace it and at that time the swith could be tested with a volt/ ohm meter to make sure that's the problem. I wish I could help more. Good luck.
