How do I put a dimmer switch in?
Very carefully..............................couldn't resist.
The Tech manual covers it install of the headlight dimmer switch.
You will have to put the steering wheel, drop the column, fishout the old switch and wires, make sure you attach a pull wire before you remove it, pull the new one into place, hook everything back up.
I did this about a month ago. The switch was around $20 and it took a couple of hours.
It also covers the headlight switch with the dashlight dimmer.
You have to push the release button on top of the switch to remove the knob.
The new one has instructions. It takes about 5 minutes.
