Question about 2002 Pontiac Grand Prix

2 Answers

2001 Grand Prix GT

No brake lights. The brake light in the back window works but not the two rear lights. I have tail lights and signal lights. Was told there is a switch in the steering column that was bad, Is this true. This switch is expensive 400 to 500 dollars so told by the mechanic. I was also told there is a switch behind the brake pedal. This sounds more realistic to me but I am not a mechanic. Can you set me straight.

    No brake lights + cruise control stopped working. I replaced bulbs, removed all brake pedal switches, and they seem to check OK with ohm meter. I checked power at the connectors, and all have power. There are 4 connectors, not sure which one is brake, but all have power, 2 full voltage, 2 lower voltage. This switch in steering column, do we need to remove the column?

If the bulbs are OK then yes it is the turn signal switch, the brake lites run through that switch, the hi mount third brake light doesn't, this is a common problem on late GM trucks and cars. I looked this switch up here is the part number.

I have a 2001 potiac grand prix with no tail lights the same bulb work turn signal an brake lights they r fine ive checked all fuses and replaced all bulbs even replaced the light switch still no tail

no, they are not the same. The multifunction switch is on the steering column and controls wipers, turn signals, and hi/low beam headlights. Dash switch is on the dash and generally turns lights on and off and frequently also controls brightness of dash lights. I had a Camry that had the same thing happening...ended up having a toggle switch put in to control the tail lights...fixed the issue.

2001 Grand Cherokee Limited- Driver side rear brake light does not work if tail lights are on. When you step on brake tail light also goes out. With lights off everything works ok.

Very common issue is the lamp assembly (dealer item). They are very bad to ground back through the tail lamp filament, lights on the path has voltage on it and the lamp will not work.
