My H3 Ac/Heat fan is not working. It heats up of course when Im driving. But when the H3 is still nothing happens. Ive looked at the fuses and they seem fine. Ive looked at the wires below the dash but from some that I can see they look ok? Help please?
My 06 h3 just had same problem, the motor control resistor pack was bad, located under glove box, mounted inside ac duct, large connector and two screws will remove it.
mine had burnt spot on connector,cleaned connector terminals and installed new pack, works fine now. I found your problem while looking for another elec problem i'm having.

Depending on the year , make , and model you have, most HVAC systems have a blower motor fan resister, usually located near the blower motor, check for power and ground at the fan resistor plug connector and make sure all connectors are in good shape, and not melted, or you will have to replace the fan resister pig tail as well.
If the fans work, (I'm guessing there are two of them) only when the A/C is on, then it means that the temperature sensor is damage. If possible, have a professional take a look at it. Both fans are OK,
I would check the relay for the fan. Most on the time there will be another relay of the same type in the fuse box. You can swap them out with each other an see if your fan starts working. there are numerous temperature sensors and of course the computer that could be the cause of your problem. To answer your question, when you turn your AC system to maximum (recirculate) power is sent to the fan constantly to ensure two things happen. One, with the fan on if keeps airflow across the radiator to prevent engine overheating. Two it ensures airflow across the condenser for maximum heat transfer even at low driving speeds. Just like the condenser fan on your house ac unit your car has one too. If you are low on refrigerant, the low pressure cut off switch keeps the compressor from engaging, but I haven't heard of it keeping the fan from working. Last but not least, the plug to the fan!!! Ive had to repair a lot of corroded wires for cooling fans on all kinds of cars. Fans Draw a fair amount of current, and the plug contacts burn with age. I hope this helps you out
only one is suppose to work the other kicks on when you turn ac on turn ac on does it come on now let me no and i can help you more from there check water level do you have the correct amount of water in resevior of car when car heats up half way fan kicks few minutes later fan should kick off with ac off of course sticking thermostat can cause car to over heat
Do not let this car over heat a blown head gasket will ensue. Locate and replace the fan relay, if that doesn't fix the problem unplug fan and use jumper wires to ground the plug then feed power to the positive side of plug to check fan, if that doesn't work replace the coolant temperature sensor located somewhere near the intake manifold or thermostat housing area.
My fan is also not working on my 2006 H3 last I heard was some clicks then nothing. My H3 warms up when im driving but nothing if its still. Ive looked under the dash and the wires seem fine. Any ideas?
im no expert and i am 15 but this happend to a car my parents had I your problem could be a simple fix you could of blown a fuse so you should get out the book that came with the car and locate which fuse is the fan
