I was quoted 4 1/2 hrs labor to replace a cheap part. How do I replace an old mercedes wiper motor myself?

Question

It will take a great deal of time for the mechanic to take apart the dash (and reassemble) to get ot the wiper motor through the dash.

Is it difficult to do myself, and where and how do I start?

I've done basic maintenance and easy repairs like replacing and packing bearings and a cv boot, but I've never touched a dash in my life. I've also never handled wiring (car is '87 mercedes 300).

Is it easy or would I be over my head...and any advice?

Answer 1

I respect your experience, but as a retired mechanic, I wouldn't tackle that one. There is a sequence you must follow to keep from doing damage. There may even be special tools to take it apart.
I worked for Ford for many years and car manufacturers purposely make things difficult for the inexperienced. And there is another factor, it's easy to get hurt on sheet metal under the dash.
If you do attempt to do it, remove the battery from the car first.
I think your best bet is a dealer..............

Answer 2

do you have any kind of maintenance book for your car like a Chilton or Haynes? If you can do basic maint., I bet you could tackle this. Taking apart the dash is not that hard...it's just time consuming...say that 4.5 hours is to take the dash off, replace the part, then put the dash back on. If you have a free weekend, no problems.

I can't imagine you'd have problems with the wiring....old cars like that are easier to work around.

Answer 3

Is it possible to go to a small independent garage to have the work done? I mean, if you don't go to the Mercedes dealership shouldn't the cost be less? That is what I have always heard. At least you know what the problem is...look at it this way...you could have had to pay to have the mechanics search and search...only to tell you that they found the problem...and that it would cost even more. My advise, find a small town mechanic. Or better yet, try the local college as sometimes they have trade schools that might be less expensive, as they are training students. Just a thought. Good luck!

Answer 4

The book says 4 1/2 and this is wireing. You never want to mess with wireing unless you know EXACTLY what you are doing. It is possible to fry the entire system if you are not carefull and that can be enough to total an older car. Your best bet is to shop it around but it sounds like the guy you went to was being straight up with you.

Answer 5

if the book says 4 1/2 hours its not an easy job. i'd get a second estimate but i suspect its too big for you unless you're very careful
