After a restoration the power windows on my 1987 suburban are quite sluggish. Using the original glass and all new window runs they seem rather tight. The power window switches are only delivering about 8-9 volts to the window motors. New switches did not help. When I run a battery directory to the motor leads at the switch the operations is normal.

So where else do I look for voltage drop?
