WH Parking Brake Switch

[Old Snipe]

Just had a problem with my parking brake switch. Even though the brake was set properly, the indicator light was lit on the dash, my HWH system would not come on and the warning light on the HWH panel indicated the parking brake was not set. Checked everything out, ended up bypassing the switch and everything worked, saved my camping weekend. Ordered new switch from my WH dealer, got it in 3 days, W0004758 "Switch-Park Brake Assm", cost $8.12, and $10.00 shipping to my door. Fastened onto parking brake pedal by one small bolt, looks to be a five minute repalcement.

Best Regards!

I hate when stuff like that happens because of the time it takes to do all the troubleshooting and figuring out "how'd they wire this thing?"...
Glad to hear you got a handle on it.
Let us know if you find out what went wrong with the oem switch.

This is a common problem. Your new switch will most likely do the same thing. Sometimes I have to hold the release lever and pump the parking brake peddle a few times to get the HWH levelers to recognize it. I can reach up and fiddle with the switch and make the indicator flash on and off. I tried to adjust it but there is no adjustment. Just crappy tolerances.

Maybe a adjustable band clamp could be placed around the switch an steering post so it can not do all this moving around. Kind of help the one bolt. --"007"

Replaced the switch, it was a 5 minute fix and everything now works perfectly. Inspecting the old switch I found a tiny bit of rust on it that caused it to fail. I don't have any water leaks so I guess I'll chalk it up to somehow the switch got wet as the bare chassis sat out in the elements before the body was put on and over the 3 years (2002 year chassis),it rusted just enough to cause a failure. Nice to have a cheap, easy fix for a change!
