I have an 87 260E. None of the power windows work. I have checked the two fues that control the windows and they are both not blown. I took a volt meter to the fuses and there is no voltage going through the fuses at anytime (with the car on, off, the switch for the windows depressed). Is there a relay controlling all the windows that can be bad? Where is it located?

Another thing, my center air conditioning vents have no air coming out of them no matter what my settings are. Could there be a bad vacuum hose somewhere that is not causing this vent to open? Where do I look?
Thanks for any replies.

For the window try to replace the fuse first.
air condition center vent not opening you must have vacuum leak it could be elements you need testing tool to check the system find a shop check for you.
hope this help.

You should replace the fuses even though they appear to be OK. Trust me they might cause this. There could be a vacuum leak in the engine compartment causing the Klima problem/
