just as the topic says my heater blower motor is intermittent

it only works when it wants to.......

its hasnt worked in monthes but it worked tonite...........

i am thinking that:

1) the motor itself is shot

2) my ECM is garbage

3) the relay is on the fritz

i say #1 becasue it is intermittent
i say #2 because my cooling fans dont always come on when they are supposed to
i would say #3 BUT i jumped the relay and the motor still did not work

help me out here guys

i want heat

in many years, cooling fan & blower motor shared a common ground. try stripping some insulation off the black wire on the blower motor power feed and running a jumper wire to an alternate grounding location. (exhaust manifolds and battery negative terminal are excellent ground sources)
