Wiper Motor Question
My wiper motor in my '72 is fried. The actual motor runs, but there's melted plastic in the housing along with a wasted relay. Can any wiper motor form '68-72 work (those with the opening vacuum door).?

68 is a bit different, I can't remember exacly how. 69-72 will interchange and many 69-70 something GM motors can be made to work if you modify the wiring. I'm using a 78 Vette (non-pulse) motor on mine because it is lower profile. I looked at the wiring in the 69 shop manual and modified mine accordingly. I think you make that red wire the park instead of it being on a different lead, but it's been a while.

Just did that a few months ago. Mine wasn't painted blue, it was black. I'll try and find the P/N if you want.

I'd be interested in that P/N as well. I rebuilt my wiper motor last week and while it works fine on a bench test I'd like to have a backup plan should it not function effectively once installed.

Well, if you go to Advance Auto, it took him all of 45 seconds on the computer to find the wiper motor. I just gave him make, model and year and voila - my wiper motor. SInce most of the franchise auto parts stores are computerized, for something simple like a wiper you don't need a part number. Now, when the kid behind the counter asks me how many cylinders in my Corvette, that is when I need to give him part numbers.
Call them. I bet you can do this over the phone. I am such a regular customer (five cars) that I can special order stuff over the phone and not have to pre-pay.

Anyway.. I got mine from Ecklers online.. Was easy swap in,but no door like the 71's..
Just burns me up when the auto parts guys ask what you need you tell them, and then.. Oh what year car is that.. i.e following the prompts on their little screen. No clue.. If they don't know the year, make and model,they are clueless... You have a what???

It would be interesting on the price differance between model's for the same part.

Sorry about that, I got the info from the release engr for the motor.
I'll let him know he's wrong.
The N.C.R.S numbers are the tag numbers
My 80"s tag is 5044907 and part # 4949864
