1990 Blower control module info
Just wanted to let everyone know what I found out when replacing my blower motor module
Symptom: Blower fan stays on all the time even when ignition is off and key is out.
Fix: Replace the BCM.
It is located at the top of the AC box near the firewall and has 2 connectors.
DO NOT buy the OEM part for a 1990, it will cost you over $100....
This BCM works and is a lot cheaper than an OEM part for a 1990 Corvette by a good $75.00!!!! Yes it really is for a jeep but is the same for my 1990. https://www.ebay.com/itm/Top-Quality-4720046-Blower-Motor-Resistor-For-Jeep-Grand-Cherokee-w-ATC-96-93/172133419893?fits=Make%3AJeep%7CModel%3A Grand+Cherokee&hash=item2813f38b75:g

There is a how to video on YouTube that will walk you through the process.
Also reference this thread.

I bought my Jeep module off fleabay over 2 years ago for ~$13.00 and it still works great and s a perfect fit, same as OEM. And, FYI, the original that came in my '90 ZR-1 has "Japan" printed on the bottom of it so I guess that was where they were all made. The only difference between the OEM and the Jeep one is that there are 3 plug contacts instead of four but one of the contacts is a dummy and doesn't go anywhere, so when you plug your harness onto it, it works perfectly. Don't count the plugs because they are meaningless.
