2003 trailblazer window wipers wont stop

Do wipers work? Possible ignition switch. Jiggle key while running and see if anything changes

popsible a bad stop switch located inside the wiper motor

A mini so it will be the same as a europeon version and i would suggest a realy is sticking but what one and where? i have no idea as apart from taking one or two to the test centre i havent worked on one

Check fuse #19 in the rear fuse panel. If OK, you may have a bad Lift Gate Module (LGM) or a broken wire in the wire harness between the lift gate and the body (in the area of the rubber boot)

the wiper control anp park are built in the wiper motor trans. easier to just replace it

you will have to replace the multifunction switch as a unit

There were some issues with ignition switches in those vehicles.It is easy to change and does not cost but about $30. Remove the column covers, unplug the switch, and depress the 2 white tabs holding it in place. Good Luck

There is a black plastic cover on your wiper motor. It's held on by one screw i think. Behind it you will find the circuit board. They are about 20 or 30 bucks. I hope that's your problem!

is there ice or an obstruction preventing the wipers from docking?they will keep running if there is.
