Headlight Module Repair Part 2(Illustrated)

[Reaper1]

The '90 HCM's *should* be the same between G&J body cars IIRC.

In '91 they both went to BCM control and there are two relays under the hood in the PDC that are part of the headlight motor circuts...

Ah, good to know. Thanks.

I would like to fix it properly one of these days.

I did this with my 90 Daytona. When I took the HCM out the solder joints didnt look bad at all, but I resoldered them anyway and now it works fine. Thanks for the helpful thread!!

Thanks to all of you guys.I finally got around to digging into the HCM on my 90' VNT.I located the unit,it took about 5 minutes of up-side-down work to get it out.I split the plastic case right down the middle going long-ways with a stanley knife (razor-blade) all the way around.I was able to pry the case apart without really damaging anything.I was also able to kind of slice around the molded rubber protectant and peel it off in one sheet on the solder side only.I lost a few small chunks but not much.
At first glance,the only solder-joint that was noticably bad was one of the pins for the plug-in connector.The closer I looked there where a few of the solder-joints for the (3) relay's that looked like they had very small cracks.All in all I re-soldered about (6) places that looked suspect.
I plugged it back in and guess what.....................YE-HAAAA !!!
It worked just like a new headlight flipper !!!
And by the way,That box is like 3W x 4L x 2 Deep.
Thanks again.
