Most of you here have been following the seized caliper thread. Mine (LR) got so hot it blew the tire and started a tire fire. Rig was towed to Reeder Chevrolet in Knoxville which are the only authorized Workhorse facility in my area. Reeder replaced all 4 calipers, rotors, pads, hard lines, rubber lines & rear bearings.
Once it was all back together, they informed me that the brake lights were not functioning. The Mech checked the wiring in the vicinity of the meltdown but found no melted wires & even said the loom was intact. He checked the brake switch by bench testing it and said it was good & when on the Coach it is functioning correctly. That there is 12v brake power at that location. He tried to trace the wires to the rear from there, but said the bundle of wires running back are all White.....ALL of them. He spent a few hours on this and then gave up before I picked up the coach yesterday.
Running lights, turn signals and flashers all work. Keep in mind that the Bounder has separate Red and Yellow tail lights(4 total). Red is 1157 dual element bulb for brake and running lights, Yellow is for turn signal and flasher.
While driving it there are some odd things going on[clues]:
-Cruise control does not work(it worked perfectly before the incident) I know the brake light switch or a fuse is usually the culprit.
-Blue High Beam indicator lamp is >ON< all the time during daylight driving, but the High Beams are NOT on. If I turn on the parking or headlights, the High Beam indicator goes >OFF< unless I flip the high beams on in which case the indicator comes on like it's supposed to do.
Before the incident, high beam indicator was never on during the day.
Before it got dark yesterday I checked both interior dash fuse panel and exterior one on the chassis. All
Brake or ABS fuses are good. I then pulled the RR brake/tail lamp assembly and found the 1157 bulb intact.
Today, I will pull the left one tomorrow and verify that both bulbs bench test as functional. I will check the trailer light harness and see if Brake lights are functional or not. Then I guess it's under the rig to inspect the wiring that runs inside the frame rail on the left side where the heat might have damaged them. I will also read any codes that may or may not show up on the Scan Gauge.
Why would Fleetwood run a bundle of multi function wires and have them all the same color? This makes no sense unless all their harnesses were pre-labeled at each end? And even then it just fundamentally seems like a bad idea.
My pea brain keeps going back to the odd happenings when driving home. I know all those things are related- blue indicator, cruise, brake lights. I just need to figure out how they are related.
I have hair to pullout, but trying not to resort to it. Maybe I should shave it all off and go Telly Savalas until I get this figured out?
