my blinkers or brake lights dont work on my 95 monte carlo?

Blinkers and brake lights have two things in common . the turn signal switch and the ground wire, have these checked by a tech.

As long as your fuses and tailights bulbs test okay as looking is not good enough, use a 12V test light to check for power and ground to be sure. The turn lights and brake lights are two separate circuits and have associated fuses with them. Where they separate and what is usually wrong when you have a brake light problem as you state is inside the contacts of the signal switch. The brake light circuit has two separate outputs. One goes to the high mount brake lamp with out anything else involved and you are saying that works. This generally would mean the other circuit should be okay to the entry point of the signal switch. Here is just travels up the switch and passes through a set of contacts which are normally closed until you engage the signal switch. So the thing to do is access the signal switches wiring at the base of the column and test the brake switch input to the signal switch. Then jump that power to the rear brake/signal circuit and check to see if the light comes on bright. If it does, the signal switch in the column needs to be replaced. Chances are if the brake circuit and the turn signal does not operate, it is the same problem, but I would still do some checking before tearing it apart.

Sounds like a short in the wiring.

it isn't the brake gentle change like others have pronounced. If the third brake gentle works such as you pronounced, your brake gentle change is effective. you have got the bulbs put in incorrectly, the incorrect bulbs put in or undesirable bulb socket holders. Do you turn indicators, tail lamps and hazards paintings usually. not blinking to rapid? examine your brake gentle bulbs back and examine the sockets that carry them in place. that's a typical difficulty to have the bulb sockets to have undesirable contacts. bear in mind. this is not your brake gentle change in the journey that your third brake gentle is functioning.

have the wiring checked, they get brittle with age
