GEM-what'll fit?

Pulled the GEM today. Wet but not really corroded.
I got one out of a 1999 f 150 today for 5 bucks with the fuse box on it.
Anyone know if it will fit a 1997?? If not then what years might?
thanks, bullseye670....................

Dude, that is BAD @SS !!!

I want to say that the 97 is a '97 or '98 item. '99 is the one odd ball, some left over '97-'98 stuff, and some pre '00-'03 stuff. That is what the electrical diagrams that I have come across tell me ( that might not be GEM specific ).

You can pull a '99 owners manual, and do a stare and comapre to your OM for the fuse section for the Central Junction box, to see if theya re the same.

When you say "not really corroded" is this cleanable ( both sides GEM and fuse ) or is it toast ?

If the pins are not trashed, and you don't want to pay the USD$ 250-350 for a new one, this could be worth a try to clean the pins ( something like #0000 steel wool ? ) and use dielectric grease to put it back together, and see what happens ?

If the pins are too far gone, it could be a waste of removing the GEM.

Let us know, maybe Steve83 will be by in the AM, to offer a better opinion, on if you should even try cleaning the lot, and reassy.

Also, if you could please take some ( A LOT ) of pictures of the deinstall, they would be worth the weight in gold to some other members here. This would be a first that I have seen. So far, only text of the job has been posted.
If you don't have a gallery here, drop me an email via my profile, and I will post them !

Pictures. No problem. Glad you mentioned it. I forget to take any when I did a similar job on the door code buttons.
Its already removed but I can take pics on the put back in and possible just reverse for the disasemble.
Both fuse panels and GEMs look the same. Gem is slightly different plastic box but otherwise looks identical.
Both have 4x2 f150 on them. There is a code on both. Three different sets of numbers. The middle and longer code matchs. The prefix and post numbers look different. Possible just a location or such. I will look inside both and compare.
Going to pull the windshield tonight if I get time.
Actually I don't see any corrosion on any connectors. There are the 2 large plugs on the very bottom that are held in with bolts. One of the had water in it. Deffinety wet, but not corroded. The one side of the solder board does look a little dark, not burnt-just not as shinny as the other end.
I will be most likely cleaning up the old one and trying it out again. Nothing really looks bad. Like I said though, I couldn't NOT buy the new parts at that price.
Going back on monday and finish removing the upper dash. My old one had some broken mounts that cause rattles. Hope to pay a similar price. Should be under 20 bucks. (hopefully). I took the speedo for 10 bucks already. Got the worn out ket cylinder the other day as well, also 4.95. That came out of a 97 mercury sable but fit exactly, works fine. Had new looking factory key in it.
I'll get back to ya, bullseye670...................

Hi bullseye670 glad to see your coming along. I work for Ford Motor Co. Kansas City, when we launch a new model alot of times the pre and post ditgits will change. The GEM and fuse box you have is probably the same.

If you need door keypad install pictures from a 2001 SCrew ( slightly different then std or Scab ) I have some in my interior gallery, when I did this on my last truck:

Right click save as or email me if you want the source pictures.

Sounds like it could have been a case of the connector filled with water causing the problem. Rain water ( as in the minerals in the rain ) will act like a decient ( albeit high resistance ) conductor. This could be the cause of the problem. If the pins are clean on both the fuse block and the GEM, a good drying out ( lay on a heat vent in the house for 24 hours ) dielectric grease and assy should take care of your specific issue ( not true for the previous GEM text, that indicated green fuzzy on the GEM to Fuse block pins most likely long term submersion ).

Seems like you are very lucky. Cheap part that appears to be a replacement, and you caught the problem soon enough to do something about it.

Good luck getting the additional items for your truck. They sound like a good bunch of guys to do business with. The large junk yard by me would want 50% of new for one that sat out in the weather, and looks worse then yours
