How do I test power to wiper motor??

[Shawninvancouver]

 i am looking at the plug with six wires. I tried my test light by grounding it and probing all six holes.. no power with wiper on.. fuse is ok... what else ? am i doing something wrong?

thanks

Grab a multimeter and the FSM and follow the wiper motor circuit from the switch to the motor. Establish that you have power going to the switch first. A test light is not the proper tool to use for debugging a circuit. You mentioned earlier you had a working motor that spun freely. Did you try that motor?

i used to have power at the switch... but i dont see power there anymore.. but i do have power at the washer plug on the blue red wire...

fuse is ok...

my motor was not working before.. and i think after i took it apart and put together its in worse shape... i just want to know my power is ok so when i get  a new motor it will work ok..

Your going to have to trace the circuit. There’s no way around it.

ok.. i have power at the wiper fuse... i have power at the wiper motor...  - is there more to it then that???

can i test the switch?? with test light in wiper plug for diff speeds?

Have to admit, the diagram is pretty hairy...

You might read some of the Honda upgrade threads.  People have dug in to the operation of the factory motor so that they can replace it with a Honda motor.  There's probably a schematic in one of them.

yes.. i getting the honda motor over next few days... i just want to make sure my power is ok -  if i have power to blue red with key on i get power to wiper motor..but do i need  to see power at switch? how can it die from motor to switch? also  - is there a way to test the other sppeds? are those wires in the wiper plug? if i turn to high speed should i see power on anther wire at the wiper plug?

can wiper wiper switch wear out?? so there is no power coming from it??

i used to always have live power on one of those 4 wires soldered on to the side if stem above key area.... now nothing,,

[Shawninvancouver]

only power to blue red.... no other power on wiper plug with car on and switch on med low and hi  ... power will not show anywhere else on plug.. is it even possilble to test for power on that wiper plug by using a test light??

It has been suggested before to get a digital volt meter. Still don't have one. Can't test for true voltage or resistance with a test light. Nobody can help you fix these things from a 1000 miles away if your not gonna do what they ask!!!

Ok.  I do have a volt meter. You want me to see volts in wiper plug? When on? Off? Med hi?
