wiper motor ?
hi guys, im in the process of making some nickel and dime repairs. my '71 has a 2 speed wiper motor, slow and slower. what do you recommend as a replacement? parts store oem? LMC? Year One? other? is there an after market unit that's faster or a motor from another vehicle that may work better than the original?
thanks ahead! -steve

Re: wiper motor ?
I have never done this *YET*, but if you had a good one, you'd probably find that it is too fast on high.
I can't recomend a place to buy one. |

Re: wiper motor ?
I put one in from a Jeep Wagoneer. The switch had a delay function. The intallation is not for the faint of heart as it requires trimming the mount under the dash and changing the arm the wiper mechanism connects to.
However, it works well and I like the delay function. |

Re: wiper motor ?
Here is one thing you could do to upgrade your wipers and it is not hard to do. It won't make it any faster but will give you delay wipers. http://www.carolinaclassictrucks.com...wiper-kit.html

Re: wiper motor ?
It won't cost you anything to clean the terminals and make sure the motor is grounded good.

Re: wiper motor ?
thanks for the input fellas.
Vet- i cleaned the electrical terminals and ground strap but no difference. i think 31 years of service has just wore it down but thanks for reminding me to try the basics first. Low'n- i'll keep your Wagoneer motor as a plausable back up idea if i don't find a decent bolt on item. a little effort to make it work dont scare me. i think?! '71C20- i have never been to that site so thanks for the heads up on it. that set up is nice but too nice for my rig! i have other items on my shopping list for LMC, but i hate to order a motor from them just to find there's no speed difference. probably do a parts store purchase here, try it and see if performance is increased. Longhorn, if i stumble upon something good i'll pass it on to ya. thanks again guys. -steve

[QUOTE=snj8198;2532016]thanks for the input fellas.

Just one little thing to add to what VetteVet said...If you have a DVOM, check the voltage at the motor when it's on high speed. There could be a voltage drop somewhere other than at the motor or ground. You should have close to battery voltage on the high speed winding (make sure you are grounding your meter to a good ground like the neg. post of the battery). ![]()

Re: wiper motor ?
When messing with these, remember, the motor always has power, it is switched on the ground side.
So it dosn't matter what the switch is set on, you should always have 12 volts or so. |
