Have you ruled out the GEM module? That is the first thing I think of when weird electrical things start happening.

Generic Electronic Module. It piggybacks the interior fuse block and controls/monitors many electronic sub systems.

I would also consider checking your grounds as a bad connection somewhere could effect multiple systems.

Ok ty tom will look into that

 

[TexasAngel34]

Im about ready to run this thing off a cliff ughhhhhh....

 

[toms89]

Here is a schematic of just some of the systems the gem module directly effects. Notice most of the systems your having issues with are identified.

It is looking more likely it may be the root cause of your issues. Could you have gotten it wet inside on your last mud outing?

Yea im thinking so .... i know the mud was so bad i had to drench it pretty bad with the hose to get it off... do i replace the gem or what... how xo i test it to see if thats the problem most of all where is it... my roommate said he will look at it... i heard it has to be dried out somehow...

It piggybacks the interior fuse block. Drivers side leftside under the dash.

Unfortunately I do not know of anyway to confirm if it is the issue or not.

I would highly recommend if you do go through the trouble to remove it you also remove the fuse block as well and dry them both out completely. When I had issues I removed both and water actually poured out of the fuse block on removal. I then set both near a pellet stove for 24 hours to completely dry them out. This fixed my issues upon re-installation.

Heres a link to my thread when I had gem/fuse block issues...

Ok tom... well ita def a pain trying to get to it... i will have him remove both ... so dry them out for 24 hrs... idont have a pellet stove but i have a portable heater i can use... i will go to the glass place and have them check for leaks as well... is there anything to help stop this lsaking problem im heafing of.... thanks again youve been such a great help...

 

[toms89]

Its commonly associated with a windshield leak but it is my opinion it could be leakage past the door weather stripping as well or possibly the engine bay if sprayed directly. There are several penetrations for wiring, cables, etc... that could potentially leak.

 

[TexasAngel34]

Got it out... no moisture all dry.. i will take a shot of it..

 

[TexasAngel34]

Makes sense to me def...

 

[TexasAngel34]

Hmmmmmmm..... well im gonna dry it out even though i see no moisture just to be safe...

 

[TexasAngel34]

Well some of fhe stuff is working now ... def gonna replace the solinoid on the transfer case and the switch to be safe...air ride finally started after we put the gem back in

 

[1koerner]

[TexasAngel34]

Ok thanks... everything except the air ride is still acting up here and there...been to cold to put in the new solinoid off the case... hoping to get it working soon... truck rides so diff now
