Is there any reasonably priced source for these things? I'll keep an eye on the local u-pull yard for the cross reference, but just wondering if anyone else has a place to buy other than ebay.

Looking inside, it appears to be a very simple circuit, and $2-300 seems crazy. Anyway, Thanks!

Check eBay for a 1997-2004 C5 Corvette headlight module. GM Part Number 16523917. If fits Fits Corvette, Fiero, Firebird, J2000, Skyhawk, Sunbird vehicles. Ebay has used ones for ~$100USD. You can try to repair using these instructions: https://www.instructables.c...t-Controller-Repair/

GM PARTS DIRECT lists this part number as a replacement for the headlight control module for late '90s - early 2000's Corvettes, '87 & '88 Fieros, and other GM vehicles so, yeah, I think it will work.

Anyone have a completely burned out unit that I can purchase and tear apart just to see if it can be modified with better quality parts?

Whoa, TFS sells them for 675$ USD. That's a big difference.

I might quite as well want to buy from GM Parts Direct for a replacement...money to be saved no question.

Thanks,

According to the web page that Mike posted the headlight module is built around a 4 pole single throw relay, a mosfet and a logic chip with some resistors and capacitors. It looks like the module energizes then detects the stall current of the headlight motors, shuts off only to be activated again when the headlights are turned on. The relay switches 5 amps and that is why GM didn't chose a solid state device back then. AFAIK there is a new Chinese made version of this module available for around $165. Eckler's Corvette sells them as it is also used on the C4 Corvette.

Great Info and a huge savings for all Fiero Owners. Now we just need someone to make up new wire harness for the 87/88 Headlight mods because the new motors are more readily available. Thanks .
