98 Isuzu rodeo power window works sometimes, when not working the switch makes a buzzing sound. It’s only the driver side window. All other windows work all the time. Also the power door lock works sometimes and makes a buzzing sound when not working. Replaced the master control switch and the driver side window does the same and now power lock button just makes a clicking sound. What should I try next.
@williswillie that sounds like bad actuators etc. Connect power directly to the appropriate pins on the connectors to the motor of your power window and see if it works then. If so it is possible that you have a ground failure etc. If it does not work it is your motor that is failing. Of course you can also try what the SM suggest
“buzzing sound when not working. “ is usually caused by a bad lock assembly. Replacing it should fix your intermittent problems
