I have access to many sunbird and saturn headlight control modules are any of them the same as the firebird ones?? are any interchangable?? Thankx

 

I can't answer regrding which years of Sunbird are compatible yet. Saturn is a no. I picked up a couple of Saturn modules before I realized they were different. Their modules have different case, but more important have connectors with more pins.

Here's what I know regarding Firebird modules. The modules from a 1987-88 Fiero and 1987-89 Firebird are the same. They used a different module from Model Year 1990-2002 Firebird. I haven't yet been able to sort out the other compatible vehicles. FYI, Fiero modules are inside the drivers-side fender behind the inner fender panel.

You lose nothing by trying one of the Sunbird modules for your Firebird. It either works or it doesn't. There is no inbetween. If it is for the wrong year it won't do anything, no power to the motors at all. If the new module powers just one headlight motor, then the module is compatible, but bad.

Corvette modules are different, too.
