survival tip...ok not really--but make sure you turn off your wipers with the switch in freezing rain/snow and just not turn off with the key as you leap out for home.i left mine on and when i used the car again a few day later the wipers turned on when i started the car and being frozen it snapped the hub that is attached to the shaft from the motor.it's bad enough ripping the rubber wiper on a frozen windshield but try finding a hub for a 92 Plymouth,my canoe hauling car that i used for the propane heater try out.i looked all over and a parts store finally tracked down the one of two in the Minnesota area for me.i guess after that i key in on wipers on snowed in cars---
