    '92 Mercedes 300 CE, heat, defrost; front/rear and air works, but fan isn't operable. Also, sometimes, when I am running the defrost for heat purposes now, all of my indicator lights come on, but the car doesn't stall. What would create these problems?

Brushes on the motor may be going bad. Blower motor is in engine compartment under wiper motor assembly. The blower motor regulator is under the blower motor. There is an A/C relay behind the fuse box under the screwed down cover.
for lack of motor speed its probably the brushes on the motor or the regulator. If no cold air your charge is probably to low to engage the compressor.

AC Heater


It sound like the blower wheel of the blower motor is rubbing the inside of the housing (the smoke). Sounds like the blower wheel rubbing may have burned the inner plastic housing or has come off of the motor shaft inside. Take the blower motor and wheel back out and inspect everything closely I think you will find the problem.

Air and heat dont blow hard any more


Sounds like you have a bad blower moter resistor.
The resistor assembly is located on the heater box module
under the dash near the blower moter. Hope this helps.

1997 buick century - blower stays on when car is off


The blower motor relay is stuck, holding the curcit engauged. Look under the hood, find the conveinence center, where you will find fuses and relays (read the cover, see if one says AC/Heater blower relay), if not, look in your car's manual, to see where this relay is located. When you find it, pull it out, see if the moter stops, if ti does , replace it.
