Which fuse was blown?
Cant do that, its against site rules.
Ok, with the key on, check for power to ground at both fuses. Let me know what you find.
Sorry about that. I was off as well.
Ok so both fuses have power.
Does the switch have any lights whatsoever?
Is there a way to check the switch and the module without buying new ones and replacing them? Continuity check or something? Was hoping maybe it was just the switch and hoping for a way to verify. Know any?
I have seen other posts on here with schemaic drawings. Do you have any of those to show me where the switch and modules are?
the Switch is the buttons in the dash that you can see. The module is behind the knee bolster under the steering wheel.
I had the center panel off and it looks like the switches are all tied together. Do you replace the whole switch harness, or is each switch separate? If each switch is separate, I would doubt all of them would go bad.
To get to the Module, can you get to it from just taking the bottom panel off under the steering wheel or do you have to take the dash apart above the steering wheel. If so, any drawings / schematics to help with that?
If the system can't communicate with the module wouldn't it throw an error, or does only the motor itself get monitored?
Last question (maybe ;) is where is the transfer case acuator motor? Is that the motor at the transfer case with the harness of wires going into it? If the motor needs to be replaced, what would that run (parts and labor)?
Ok. Took it in today. They are telling me it is the "transfer case shift module". Is this the transfer case control module you were talking about or is the "shift" module something different? They are telling me it's a special order part, up to 1 week to get it (Michigan is the only place that has them), and it's $442.99 for the part and 1 HR to install and 1 HR to re-program.
Sound about right? I am not sure how they determined this, they wouldn't tell me - "the mechanic is busy" they told me. Does this sound right? I checked last night and I had power going to the transfer case control module on the orange wire so I know there is power going to the module.
Thanks for helping with this.
I could get the part online and a programmer for a little less than what they are going to charge me. How hard would it be to program (the VIN I am assuming) the module? In that case, I have it for the next issue I run into - as I plan to keep this vehicle for awhile.
Let me know.
Thanks again for all the advice
