How to replace windshield wiper motor.

[royp4]

I need help replacing the wiper motor on my 996 cab. Car was covered with ice from winter storm. I let it run for 15 minutes and apparently wipers were on intermittent. Had electrical burning smell when I got in car and wipers wouldn't work. Don't understand why fuse didn't blow in order to save wiper motor. Any and all info deeply appreciated. Thank you.

Are you sure your motor is bad and that the linkage is not slipping?

(I removed your other 3 messages that all said the same thing - one post per topic please)

First of all I apologize for the multiple posts. I'm pretty sure the motor is dead as it seems to be the source of the burned smell. I removed the motor and am pretty sure linkage isn't slipping.

This was done by one of the guys on PCGB, and may help you. Bear in mind it is a right-hand-drive car in the DIY:

LOREN I THANK YOU SO MUCH FOR YOUR HELP AND RAPID RESPONSE. I am still curious though why the fuse didn't blow thereby saving the wiper motor. Any ideas? Thank you again

Hard to say - was it the correct fuse rating?

I'll check that at my first opportunity. Thank you again.

The motor would only blow the fuse if it had shorted to ground. If the brushes had worn out, or a wire burnt inside without grounding, for example, it would just stop working and not blow the fuse.

Sincere thanks to all who offered suggestions. I finally had time to install the rebuilt wiper motor I got from advance. My wipers work again and just in time for a south Carolina thunderstorm. You are all awesome.
