Non F-body heater question for mom's car
hey guys,
My mom has an 88 Beretta GT... not a bad car, high mileage though... but nonetheless, it's been good to her.
Okay all of a sudden her heater doesn't turn on. turn it to 'on' no clicks, hums or ANYthing. we checked the fuses and they seemed good.
any idea? any help would be apreciated.

Garett,
Does the blower fail to operate at any speed? The highest speed is powered separately, through the high blower relay. The three lower speeds are controlled through a set of resistors in series with the blower motor.
If the blower doesn't run at any setting, Tempest could be right - the blower is in the toilet.
If the blower runs at high speed only, check the relay and resistors. If the blower motor is properly grounded, and has power at the terminal on the housing, try tapping the motor with a screwdriver handle or wood hammer handle. If the motor tries to run briefly, the brushes are probably worn and are sticking in their holders. This would also put the blower in the toilet.
A replacement motor is about $30.00 (US) and is not too difficult to replace on most cars. In a Beretta, I'm not sure. I've never had the pleasure of working on one. Rumor has it if you have the 3.1L engine, the alternator may be in the way. Otherwise, it's a fairly straight shot.

If the motor is good, take a look at the single most common cause for complete failure of the A/C system in GM ars through the 80s...
Pop the A/C control head out; take a look at the wiring to it; you will find among all the othe wires a single brown wire that splits off from the rest and goes back into the dash where it plugs into the main dash harness. This wire supplies power to the control head. Now look at the connector where it hooks to the dash harness; it's a black thing of extremely srupid design. I'd be very surprised if it isn't burnt to ashes like they always are. If so, cut both halves of it off and replace it with a set of BIG insulated spades (not the regular sized ones).
I've seen this problem in my Camaro; one of my little brothers' Camaro, another little bro's Monte Carlo; my wife's Buick; and my mom's Celebrity. I think it might be common.
