blower motor
I checked the connector at the resistor module and its 14vdc so I assume its the resistor board. Having a problem getting the last bolt out in the back to remove it. I noticed by picture on the new it has an IC on the board. Is it possible that a battery charger took out the board. I jumped the car the other day with a 200amp charger.

What HVAC system do you have??? ... The MANUAL Controlled system or the Dual Climate Controlled system??
Each system has a different blower control module. The manual system uses small resistors to control blower speed. The dual climate system uses a digital module to control the frequency to the motor and is a LOT more complex and expensive.
The rear bolt holes on the module is/are SLOTTED so all you have to do is loosen the screw to get the module out.

Bill,
I have the auto dual unit. From looking at the schematics, the manual one has more pins. the auto unit has 3. Is this correct. I used the p/n 89019166 and a bunch of units come up, $18-40 and they claim to be for the auto unit. I pulled the mosfet, voltage regulator, and 3 caps and they all check out ok. The only thing I cant seem to check is the TI integrated circuit. Cant find it any where. All the traces look fine.
Also, anyone have the specs on the fan motor, resistance and current. If its pulling too much current it could hose the switching power supply.

Send me an e-mail address and I will send you some pictures of what I have..
I have a pic of a disassembled 2002 unit. The black plastic cover has a PN Tag and the info on the tag is:
VALERO ASM MEXICO
52479971 025-1-B
Hope that helps..
