[CONVGTMUSTANG]

I'm having sorta the same problem. My emergency flashers and map lights are not working. The wiper motor is staying on, even with the switch being in the off position. I tried replacing the muti function switch and the motor. I hoped this would solve the problem, but it didn't. There is an old alarm system installed in the car. I think/hope that this could be the problem. I'll also check to see if the ground strap is on properly. Hopefully this will solve my problem and yours too. I'll let you know.
