Intermittent heater blower

My 94 Explorer's heater blower works for while, then goes off, a while later it'll go back on. It may, or may not work when originally turned on, but either way it'll work for a while then not, then work and then not .... and so on. It has to be turned on for this to happen and happens at all speeds.
What's up?

Same, same. Hope you got it fixed. If so what did you do?

Sounds like it could be a bad breaker. It will kick out and then reset. If a new breaker doesn't fix it, then it sounds like the blower motor is pulling too many amps for some reason.

I also have a 94 and had the same problem. The blower motor would go on and off when it wanted to. Try the blower motor relay.

Thanks for the suggestions. I didn't hear "computer" anywhere which is good. Breakers, relays and wire I can do. Thanks again.

Working better now. Bad blower motor. Tap it with the handle of a hammer and it would start to run but seldom would start on it's own. Current draw very erratic. Thanks for the suggestions.
