when i bought my 89 all the electricals worked. now my left tun signal doesnt work. the right one does though. now i realized when i took my door panels off that if the passenger switch is disconnected the window wont go down even if you use the passenger switch from the drivers side. so i guess some of these electronics are running with one another. is there anything i may have disconnected that could be causing it not to work. any help would be great. if i use the hazards only the right one works. idk if that helps.

Have you checked both front and rear LH side turn indcator bulbs to make sure they are good? Are the bulb sockets clean and not corroded?

The electic windows are on a separate circuit from the turn indicators. So if the turn signals have problems, it will not affect the electric windows.
