rv - Windhsield washer reservoir, pump, and switch, radiator cap, waste tank heater
The windshield washer dash switch was broken. With our upcoming winter camping trip, I figured the windshield washers needed to work so it was time to fix the switch. I installed the new switch, using the same momentary lever switch as original. Then I tested the system and got nothing. Turns out the pump was siezed. Better yet, the plastic fluid tank was cracked like crazy. It held water (amazingly) but had a severe leak.I ended up replacing the entire assembly with some universal unit from the the auto parts store. The new tank is tiny, maybe holds a quarter gallon, but the original tank was equally tiny so nothing lost there. The new tank and pump work great and its nice knowing I can wash the windows from a switch if desired.
I also replaced the radiator cap since I don't know how old the current was one. The new cap came from applied GMC so I trust the rating of 7 PSI even though the manual says 9 PSI is the right rating. The old cap was rated at a whopping 16 PSI. That high of a pressure rating could have damaged the cooling system.
