Touch Drive dead. Fuses?

[hilbile]

I went to use my touch drive the other day after I thought I fixed it. Corroded connections to the motor at that plug. Well I hit the button and it clicked but didn't engage, I went to hit it again and it went silent. I assumed it was a fuse, checked every one in the block under the dash and they were all good. I searched the forums and found a locked topic about the newer touch drives, 3rd gen i believe and troubleshooting them. It spoke of a fuse block under the hood with a maxifuse that also went to the 4x4. I looked under my hood and did not see anything like another fuse block. My truck is an 88 with the 2.9L. Am I blind or what else could cause the whole system to go dead like that? burnt up wire, motor, or circut board? I looked underneath the truck and up at the buttons after it quit and didn't smell anything burning or anything out of place. Any suggestions of where to start when I go home for winter break?

the fuse box under the hood on my 89 is on the left right behind the battery i would guess its the same on the 88 and if thats all good look behind the drivers seat at the tcase control module you may have to pull the cover but theres a white button on top beside a red LED try pushing that with the engine running, then press your 4x4 button again, i used to have to do that to mine a lot, and if neither of those work you should run the diagnostic on the whole system theres a great page on it in the tech library

I plan on doing this after I get it so it will work again. I have seen that write up already.

I forgot to mention I have an xcab truck. Would that move the control module to somewhere hidden like behind the jump seats under the speaker? Dircetly behind and under the seat there is nothing that looks like what you are speaking of.

the point i was gettin at is its possible it aint working because you havent cleaned it yet. My 4x4 didnt work like yours and I cleaned the carbon off hte shift motor and it eliminated the intermittent shift. All works good now for a year and a half.

Otay. Sorry I misunderstood. Thats gotta be it too. Today I hit it and it worked, granted it was 32degrees today I like my snow, now its blizzarding out. Tomarrow i go home for semester break and I am tearing it apart to clean it all out good. My dad of a mechanic was wrong saying it was only in the wiring.
