Not sure where you're starting, but it is a piece at a time proceedure. The large can on the fire wall for vaccume, has a black rubber plug on it. Pull the plug out and activate the linkage by pushing in on the diaphram. ALL the movement starts there. There are also two switches on the left right side that are vaccume operated that syncronize the door opening and the PARK position of the wipers. If they do not work, you're stuck. Trial and error with the rest. Go slow and be patient. Vaccume, electricity, syncronize. When in a pinch, rain, you can open the door by hand and run the wipers, then close it by hand. The by-pass switches under the steering coloumn can assist in the door opening as well. One is for the headlight doors, one is for the wiper door. They are vaccume by-passes. "
" I hope not!
