catalogs show one wiper motor for 68' models, and a different one for 69'-72' models....does anyone know the difference, and will they interchange? thanks, Rick

shmoky

the wiring is different on the '68. do a search for Willcox and the 68 wiper motor.

Found it. check this out.

A=1 Cardone has the motor available...#41-146, 1968 only at most parts stores and possibly some Vette stores too........

Raz.. Interchange would be a royal pain.

You can find a ton of info on our site about the 68 motors too.. Here is the main link to all that info.

thanks a bunch everyone! (maybe that's why my wiper motor started smoking as soon as i hooked up the battery after installing a new engine harness! LOL)

i will look for Cardone unit locally, if i can't find it hopefully Willcox has one.

Ironcross...what does "A-1" mean??? Rick

razman

Ironcross, nevermind my question about A=1....when i stopped at the parts store tonight i figured it out...i ordered a new (rebuilt) 68' only wiper motor, the part number is actually Cardone A-1 #40-146. thanks again! Rick

Raz.. did you bench test the old one? 90 percent of the cores turned into us are good motors...

I have a video on how to bench test your motor on our web site... just enter the year, select tech video's from the middle box and search wiper... you'll find it. I'd hate to see you buy one and have the same issue. .. .

thanks Willcox, i checked out the video, very cool, i will bench test the old one when i pull it, plus i can bench test the new one that i ordered. i didn't have the ground strap on the other one, (the strap that goes from one of the grommets to the casing on motor) do you think that is what caused me a problem with the other one? i now have the right grommet with the ground strap for when i install the next motor. thanks, Rick

What was the old motor doing? If the old one works on the bench test then take the new one back.

razman

the other one was SMOKING, (if i would have had a blanket, i'm sure i could have sent signals).....i had just put new engine harness on, and hooked all the wiring up...engine started fine, etc, but wasn't long after i can re-connected the battery, i noticed the smoke, i pulled cable from battery immediately, and wiper motor was hot to the touch for quite awhile. i figure it was either a defective unit (rebuilt) OR, while i was "attempting" to test it with 12v and ground prior to wiring harness, i may have smoked something, the only thing it would do it rotate in park position. OR, since i didn't have the copper ground strap running from grommet to case maybe that presented the problem??

btw, i just received a new turn signal switch, and was testing it out via your tech procedure....Continuity was perfect on everything, EXCEPT last step when you check flashers.....i got continuity on post 1,2,3,5,6, but not 7???? are you sure i should get continuity on 7 in flasher pushed in position? thanks a bunch, Rick

0Willcox Corvette

Rick.. I wrote that a long time ago.. you'd better let me check it tomorrow. Where did the switch come from?

Ok.. looked at my three year old paper.. lol.. yes.. it is correct. With the turn signal switch in neutral...

razman

i actually tried to order from Willcox, but you guys were out of stock, and not sure when to expect more....i got this one from Keen. but definitely no continuity to 7 post while in nuetral position and flasher button pushed in. i guess that means i won't have flashers?? maybe i should contact vendor and ask them about this concern...certainly not complaining about any vendor here, they were very professional and sent part right out. thanks, Rick (it's not like they make the parts, and most likely it comes from same source most vendors use, if not all vendors)

0Willcox Corvette

Yes you are correct... and I wish others would follow your lead with that kind of attitude.. It's great to see someone take things for what they are!

razman

ok, now i feel like a REAL IDIOT...turns out i can't count up to the number eight...for some reason i was thinking there were 7 terminals on the harness, so when i checked continuity, and got to the last one, i ASSumed i had nothing at #7, but was actually on #8...i just went out to recheck it, and realized my mistake. so, since it ohms out ok, should i be ok with this switch, or are there other problems that tend to pop up down the road? thanks, Rick

0Willcox Corvette

Naw.. if it tested out you'll be fine... the defective ones don't ohm out...
