I have replaced wiper motor 4 times last three years, wipers come on by them self run minute or 2 shut off, and it seems to start after I use touchless car wash. After I replace motor wipers work fine for 3ish months then the problem starts all over again. I bought car with 3000 miles on it, 8 years ago and has been great except for this problem, please help. 99 hardtop (fixed roof) corvette Thanks Walt D

what car, what year? gee? a suz, what?
it can only be 4 things. (all cars)
1: the wiper motor is bad. (it has contacts inside for timing.
2: the wiper shaft is stripped, nah you said both stalled.
3: the wiring is bad.
4: the combo switch for the above is bad.

DIY, with what , no tools? no meter.?
with no tools one can only GUESS,
roll dice, and replace a part.
after spending $500 on parts and the wires are good then what.
yes, buy a meter.

it could be a bad ground wire.

when you turn on most wipers, the combo switch sends
that signal( just 12v ) to the motor.
the motor is self booting, that is , it only needs the start up
and then it self provides its own power,
ive restored wiper motors, many.
then the motor runs until it his the dead spot in ITS, internal
sustain switch and the halts. if the combo switch is off.
but if the wiper fails to return, this is a bad wiper motor.
(overloaded by ice, sure)
the motor can fail 2 ways, but
id say the sustain switch is at EOL. end of life.

this is the most common design.
check your FSM for yours. the factor service manual.
or alldata dot com. sure.

How to change a wiper assembly & repair wiper mechanism on 2004 Audi A4

First time you must diagnose why windscreen wipers going slow and/or stopping.
In order to find out the cause of wipers stopping you can try follows:
1. Carefully extract the wiper arms from their axles (two pieces). In some cases you need to use an extracting tool. Heed of the windscreen !!!
2. Disassemble the plastic covers from the bottom of the windscreen.
3. With the bonnet up you can start the engine, (transmission in "N" or "P" position and parking brake on). Now you must switch on the control lever of the wipers, and go to the engine compartment. If the wiper motor runs let the wiper motor running for a few minutes and switch off. Go to the step 4. If the wiper motor do not runs you must check first the electrical feeding of the motor. It is necessary to unscrew three bolts of the mechanism and disconnect the electrical coupling (difficult assurance). If the electrical feeding is OK you must replace the motor - steps 5, 6, 7. If not, you must check electrical connections, the control switch of wipers and electric cables.
4. Now you must check the two bearings of wiper mechanism with your hand. In the most cases the left bearing is out of order (is very hot). This is the most encountered fault of the wipers running at Audi.
5. For have enough space to manipulation the wiper motor together with their mechanism you must extract the plastic cover of the engine computer box, and extract also the box screws. Then you can move slowly the engine computer box, just for a few milimeters.
6. You must disconnect the electrical coupling of the motor (difficult assurance), unscrew three bolts of the mechanism and extract together with the motor. You must move them slowly between windscreen and engine computer box until the wiper motor go out together with the mechanism. This is the most difficult operation!
7. Now you can repair the bearings, replace entire wiper mechanism or replace the wiper motor. It is not very simply, but it works.
Heed of the windscreen !!!
