ABS and TC lights

[guruerror]

Got the truck back from the dealer yesterday...their diagnosis regarding the ABS/TC lights is that I need a new ABS module AND wiring harness ($1,495 installed).

They went on to say that the ABS/TC issue is NOT related to my inability to shift my transfer case. They said that I need a new encoder motor ($641 installed).

They indicated that both the ABS module and the encoder motor suffer from water damage. While I agree that they have both seen a lot of water I find it hard to believe that they both failed from water damage simultaneously. These components seem to have a fairly water tight construction and the connectors all have water tight grommets and were VERY clean and debris free when I inspected them.

I'm sort of feel like they're using the 'shotgun effect' to fix this problem...basically, replace a bunch of parts to fix one problem instead of figuring out which part is the actual culprit.

I've asked them to send me over a detailed estimate outlining the part numbers for the items that they would recommend replacing...at the very least that will give me a little more to go on. I'll post back once I have that in hand.
