1975 cj5 wiper motor install

New guy here and first post. I apologize if it's in an incorrect forum, and I'm sorry about my "novice-ness!"

I'm trying to install a new wiper motor. Let me preface this by saying, it was a BEAR getting the nuts and bolts off of the windshield frame. Oi vey!!! Damn things broke right off!

It's a three wire motor. No pump. I'm even having a bear trying to take off the switch off the dash. (Stop laughing!)

I'm seeing switches with 5 prongs. Is this the one I need, or do I need one with a three prong? I've googled and amazon'd the switch and they've all got 5 prongs.

thanks!

It might have 5 poles but you only need the 3. Use a DVM when you get the switch to check. Is it a rotary switch? You may end up with dead spots on the last 2 if it is. You can just jumper them to the 3rd position "high" to avoid confusion. Mine had the multiple positions but I ended up with a 2 position switch, low and high...I don't have a top here in florida so the wipers are really useless for most purposes.

Awesome pics! this will help me!!

Do I have to take off my entire dash panel to get access to the backside? I'm have a hell of a time trying to get the knob off the front.

Thanks so much!

Not sure if the 75 is the same or not.

this is my knob that I finally removed! No springs or clips.



Now....new problem. I got the new motor and I bought a new switch. I replaced all the previous wires to the same spot as the previous switch. Aaaaaaand,.... nothing. Did I just waste $96 dollars on amazon by getting this new motor???

Is that what the knobs are supposed to look like on a 75 CJ? I've been following your thread and wasn't expecting to see that. Post a few pictures of both your old and new gear, as well as your hook ups. Fuse is good? Sounds like it's time to get the JF electrical gurus on speed dial-

John,

I didn't mount the motor. I just sat in the driver seat and attached all the wires to see if it worked. Should I mount it and then retry?

Or attach a ground wire to one of the mounting bolts.

Mounted the motor. Nothing.


Checked the fuse. It doesn't seem blown. Just rusty. The fuse slot is labeled radio/wipers. Radio works, so I don't know. Going to replace the fuse and see what happens.

Do you have a test light?

That will help you in trouble shooting.

You can get them in Walmarts.

If the radio works, and it's on the same fuse then the fuse isn't the problem. Unless the radio was wired up differently than stock.
