if your switch is located on the dash on the left side on the steering column, you will need to remove the access panel(s) under the column and carefully remove the wiring plug from the back of the switch. You should then be able to very carefully squeeze the tension tangs on the top and bottom of the switch (again, from behind the dash) and carefully push the switch through the hole.

If the switch is located on the heater control panel above the radio, you must remove the entire radio assembly, then remove the heater control panel being VERY careful to not break the clips that hold the control cables to the control panel. There will be very little room to move the panel around until you free the cables from the panel. Once you have the cables free, you can remove the tension washers to remove the vacuum lines and remove the wiring harnesses. You may also need to remove the control panel from the face plate to access the screws that hold the defrost switch. Reverse the procedure for reinstallation.

In most cases you will need to replace the turn signal switch on the steering wheel for your 1983 Chevy Caprice Classic rather than fixing it. To replace it, remove the horn pad and then use a steering wheel puller and compressor to remove the steering column. You will then remove the signal along with the wiring harness and bus fuses. Replace the signal and wiring and then replace the steering column itself.

Not all 91 Caprices came with rear window defrosters. You have to look in the glass in the back window to see if it has the small wires inside. The switch is usually on the right side of the climate control panel under the radio.
