Hi all,

I am a first time poster, but need some help. I have scoured the threads and have not found my exact issue. Since I bought the vehicle the 4WD selector switch has been dark and I have never had an indicator light on the dash. I tried pulling #8 under the hood, but it did not help. I then pulled #48, blown. After replacing #48 (4WD) under the seat, it keeps blowing.

I thought it might be the TCCM after reading the forums. I bought what was described as a working unit and installed it yesterday. #48 still keeps blowing. I checked the wiring diagram and subsequently checked #1 under the hood (air ride) since it's on the same circuit, but it was not blown..

Please help!!!! what should i check next?
