Why my 1996 ss impala turn signal and brake light don't work
SOURCE: 1996 Chev Silverado K3500 dually, no brake lights
The chevys with red brake lights and turn signals do two things and I've fixeds alot of them. Looking at the tail lights with the hazard flashers on. both sides flash with nothingeles on? Or are the hazards yellow? if they're red and the third eye does work the turn signal switch is possible problem but it doesn't let the blubs and the circuit boards in the taillights out as they can fail and do some really bad stories the wires for the brakes and the turns and the hazards are the same ones and if the turns look right and the hazards look right then the turn signal switch transmites the turn too as this doesn't work part of your story can't be true

The brake lights are routed through the signal light switch.
Looks like that will be the next switch to replace and the problem.

check fuse under hood, batery terminals coroded wire at harness if everything fails run a hot wire to rear brake line with an interuptor.
check the swich under the foot brake.

SOURCE: secondary fan on impala SS 1996 not operating. fan
The PCM controls these fans via certain sensor inputs, ( CTS ) and switches ( A/C compressor for instance ). When relays are removed, both relays sockets should show 12v constant ( battery voltage on "switch side" ). When the key is rolled on, there should be 12v appear in two more places, ("Coil side" ) the relays are then operated by a ground signal from the PCM. ( Powertrain Control Module ) You need a scan-tool to check for fan request, by the PCM. A/C compressor request, etc. If you have any DTC's then repairing them may well fix your problem, otherwise, you may have a faulty PCM.

Open hood. on top of headlight assembly you will find 2 small bolts. I believe a 10mm. socket should fit. Take the 2 bolts, out and remove complete assembly.
