You da man Alanh. I'll spend a few moments on the housing. I've found an Amazon assy for $50. If its not worth the repair, I may just pull the trigger on the new unit.I don't have one to sell you but this failure is 'A' Typical of some of the aftermarket integrated T/S's
There use to be Lots of Press on this Forum of the DIY repair for this particular failure. You'll need some patience, a Dremel tool or equivalent, X-ACTO knife, solder iron & silicone sealant!
Thanks for the diag input. I'll try the load resistors next to take advantage of the running lights up front.
