Question about 1994 Pontiac Trans Sport

1 Answer

We just replaced the ECM on my 1994 Pontiac Trans Sport and solved the irregular starting problem. Still need to figure out why the radiator fan, automatic windows, interior fan and heater won't come on. Is there a relay that controls these items or a fuseable link? They all just quit at the same time.

    Do you know where the body control module is located?

    That sounds like it might be the problem. Have not found any info on one in the manual.

There are GM service bullitens for these problems on your year of car, suspect the BCM is the problem.

How do I rotate the motor forward on a 1994 pontiac trans sport

I think this motor has supports on the front that reach from the motor to above the radiator. You need to take the bolts out that hold it to the radiator and then you will be able to move the motor forward several inches.
