My Blazer started acting up after I replaced the heater blower motor. The Blazer will start and run till the engine warms up and then the spark dies. Once it cooled down it would restart. I replacer the ign. module with no luck. It also died when the door is shut hard. Once, it wouldn't start till I shut driver door. I checked all grounds that I found, all tight and clean. Help, where is the PCM????
I cannot locate the powertrain control module(PCM) in my 1991 Chevy S-10 Blazer. on 1991 Chevrolet S10 Blazer

The most likely place for the PCM in your 1991 Chevrolet S10 Blazer would be behind the glove box or behind the kick panel on the right side of the passenger foot well.
