Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi, I'm Ron and I will help you. If there is power and ground to everything and you just hear clicking, then the window regulator is bad. This is a very common problem too. Hope this has helped you, please let me know, and I will still help you even after you have rated me.
Ok, sorry, with all that said, it has to be a bad ground in the switch area or a bad pin in the connector. Remember, the motor has a separate ground, that's why you get it to work by supplying power to it. Hope you find it, or just run a separate ground from the switch, that would work too.
One more thing, "clicking" ALWAYS means a lack of either power or ground. It's there, just not enough of it.
OK, as a last resort, then the power door module for the driver's side is bad. All other windows work fine, this is all that's left as long as you did voltage drops on all the circuits. Thanks again for your question.
here's what I have for you, please remember that this module requires programming too. Thanks again, please don't forget to rate my service.
