Washer Fluid Motors/Wiring

Hey guys, I spent tonight trying to figure out why my washer fluid wont spray. I took off the two motors on the bottom of the reservoir and I bench tested them with 12 volts and they both spun. I took the multimeter to the jeep and tested the connections and got 12 volts while twisting the washer fluid switch forwards on only one of the two connections(the one on top in the picture blue insulation). The other set of wires were not getting any voltage.

I connected the motors back up and nothing. I tried just connecting the wires that were getting power but still the motor wont spin. Any ideas?

Two motors???? Does your rig have a hard top with rear wiper?

Just swap the tubes so the good motor works the windshield

I just picked up a washer bottle from ebay because the PO had removed mine for some reason... motors seem to be cheap tho.

More than likely the switch is bad on the steering column.

Same thing happened to mine. I just power mine now off the battery through a pressure release switch I installed on the dash.

Yeah The switch seems to be the common Culprit. if im getting 12 volts to the connector yet when i plug in the motor it still doesnt spin, (not getting enough amps to power it!??)
What's the easiest way to get to the switch?

You have to partially tear the steering column down to get to it.


That's why I just got a cheap switch and wired it up. It only cost me about $5 and 20 minutes.

I'll fix it right one of these days.

This is what I'm going to do for my hardtop sprayer. Anyone know where to get oem style switches for the hardtop in case I change my mind?

Wait, you are getting power to the connector for the motor? Are you reading across the connector or do you have the other meter lead on ground?

Because the washer pump grounds at the stupid OEM sheetmetal screw at the headlight.

I'm getting the same issue with my horn. I read 12 volts across the connector going into horn, horn bench tested good. I removed center steering wheel cap, cleaned the depress plate and all contacts. I can hear relay click when I press horn. I removed that center cover again today and I see what looks like I'm getting a short when I press the horn(faint spark).

Should I be checking voltage a different way?
Trying to sort out my common electrical issues

Could this be my issue or you guys think its the switch?
The washers move 3 times but the fluid motors never spin.

how did you measure the voltage, with the ground on the connector or on the chassis? the ground can be an issue on any electrical. if you measured it to the chassis then measure it across the connector.

I measured both ways and got the same readings...?
