My mom has a 2008 Crown Vic. She was at my place today and said her wipers stopped working on the way over, so I checked the fuses and voltage at the fuses, and everything looked good. Checked the plug on the wiper motor, giggled all the wiring around, etc. Then I tapped on the wiper motor twice with the butt of a hammer, and they started working. Turned the car off and back on, still working.

So I told her she likely needs a new wiper motor, to which she said she’s already done that. She’s put 1 used wiper motor and 2 brand new wiper motors in it in the last 6 months. A few weeks ago she also replaced the wiper/turn signal stalk/switch.

The fact that it started working when I tapped on the motor leads me to believe that’s the issue, but it seems strange that it would be bad already, and that 4 would all go back in a 6-month period.

Any ideas? Is there something maybe causing these motors to fail?

I want to turn my 19.5 into a fairly dedicated suppressed gun. Like 90% suppressed shooting. What should/needs to be done to make it run as efficient and effective as possible with a can?
