01 mpv windows work off and on making a eeeeenk sound when there not working

Did something get spilled on the window switch?:) If no noises and now just wont go up...does the window motor make a sound when trying to lower? If not, probably the switch is defective. You can have an auto electric shop, or good mechanic test the switch...or if you have access to a guaranteed used switch from a salvage yard or internet...changing this switch should restore the operation. The window motor or regulator could be defective...but usually the switch is the first problem...if something was spilled onto the switch, you can try a hair dryer to dry out, and retry...Hope this helps.

-----------This will help.Thanks.

Start with the fuses or relay

Interrogate the headlight relay in the engine compartment relay box to ensure the switch is working. If yes, check the relay for proper operation.

Please see my tip at http://www.fixya.com/cars/r6022358-relay_check and let me know if you have questions.

Sounds like the starter motor has gone out, replace it.

Sounds like a brake caliper getting hung up.

If you can hear the window motor working ,the drive belt is probably broken ,that is to make the window go up or down .
If no sound ,the wire's in the door jam are probably broken ,you can test this by using a test light.
Also, check the electrical connection's on the window motor,and make sure they are not melted.

Remove door panel to check wiring to switch and motor
See if motor is getting power through the switch - if so motor is bad
If no power to motor check operation of switch - jump wires to test
if window works bad switch

thanks.

Try lubing the channel the window rides in (sides) with paraffin or candle wax. Motors do get weak over time.
