My heater fan quit today....fuse is fine...anyone had this happen? No funny noises, just quit. Any ideas?

Anyone?

Only thing to do is,,check with a test light for power and ground at the motor itself(with the switch on high of course).....ya got power and ground,,ya need a motor,,no its no uncommon....I had one from a customers car,,, she said it made a horrible noise for awhile,,,then started to stink abit,,,and then quit altogether,,,,,,turns out a little mouse somehow got in there and decided totake a runinside the squirrel cage,,he couldnt keep up...LOL...what a way to go..

It may justbe your resistor. (Circled in pic)

Thanks guys. I was looking through my Haynes manual and this is a much better pic. Blower motor at top of dash?

Does it work in any speed? If it works on only high, then I would say to replace the blower motor resistor. You don't by chance have a Power Probe, do you? Those things are kick ***. You can put power or ground to anything with a flick of a switch. You can even measure voltage now. They are a mechanic's dream, it cuts diagnosing time in half.

No - It doesn't work at all.

Then you have to start doing some diagnosing. Check wire harness connectors, check for power and ground at the right points, check your switch, etc...
