Can't find fuse for tail lights or multifuction switch on 2004 grand am.

SOURCE: Dash Lights

Check your fuse there could be a wire for the lights on the factory radio touching the aftermarket radio.

SOURCE: Both Tail lights and dash lights are out. Fuse is OK

I had the lights on my dash and tail lights go out on my 1995 Grand Am 3.1 V6. After much investigation, it ended up being that the turn signal switch had gone bad. I got mine at Autozone - $79.99 for one with cruise, $69.99 for one without. SW860 for the non-cruise, SW859 for the cruise version. It is sometimes referred to as a multifunction switch - however, when I called and asked about that, it seemed as though the parts are NOT the same (MFS was much more expensive). Make sure you specify turn signal switch (that also controls the tail lights, headlights, etc).

In order to replace it, you need to remove the cover around the steering column - we couldn't get the lower part of the cover off and subsequently also had to pull the steering wheel (which also meant disabling the air bag), then remove the bad turn signal switch (which also controls the headlights, parking lights, tail lights, etc), pop in a new one, put everything back together (re-enabling the airbag) and then you can enjoy a life of dash lights and tail lights once again.

SOURCE: Tail lights don't work, but brake, flash and hazzard work.

generally when the fuse is ok and the bulb is ok the problem is corrosion of the ground wire and connection to the frame, or corrosion in the bulb sockets. for starters go to any auto parts store and get an aerosol can of contact cleaner especially for auto bulbs and connections.

THIS WOULD HAVE NOTHING TO DO WITH THE DASH LIGHTS... WHEN YOU TURNN ON YOUR PARKING LIGHTS YOU SEND POWER STRIEGHT FROM HEADLIGHT SWITCH TO THE DASH...NEED TO RECHECK PARK LIGHT FUSE...IF GOOD THE BAD HEAD LIGHT SWITCH SOUNDS MOST LIKELY

clean the computer lead interface. my buddies car did the same thing, we cleaned the computer leads with a good eletronic spray cleaner and it fixed the problem.
