Itermittent heating issues, 1998 88.......

HI all,

My fathers car has been having heating issues with his 88, has the 3800 in it..... While the car is warming up to the operating temp the heater will work, once it reaches that temp, it stops........ Any thoughts, opionons, advice or options?

Thanx all, for your time!

What stops, heat or blower?

HI all,

Thanx for your interest!! It is the blower that stops, could this be the resistor?

See if you have 12v to the blower when this happens if so and the ground is good, the blower is bad, if not suspect the relay/resistor.
