Check to see if you have a blown fuse. This is often the case. Also you may try pulling the rear lights out and inspecting them for any damage or loose wiring.
If the brake lights do not work on Chevy Venture van 2000, try to disconnect the brake switch. Then short the two contacts of the connector to check if the brake lights are now working.
Check to see if the brake lights work. Had a mustang that the brake light switch activation would release the shift locking mechanism.
Check the fuse, check the bulbs and check the brake light switch, in that order.
Bad switch, bad relay, short to ground in the circuit.
check the fuse, brake lights have their own, & check the brake switch at the top of the brake pedal
Check the park lamp relay. It is probably next to the fuse.
Blown fuse or bad headlight switch
You might have a bad brake light switch. If you don't have brake lights the switch is bad. When your brake light switch isn't working it wont send a signal to the shift solenoid.
Check the fuse first, then the brake bulbs. When you press the brake, it senses the brake lights and let's you take it out of park. This happened to me - 2 brake lights burnt at the same time with one already gone, and I couldn't get it in gear. I replaced the bulbs, touched the brake pedal and she went into gear no problem.
my Oldsmobile alero did the same thing. It turned out to be as simple as a blown bulb in my tail light.
Depends on in which way they are not working / in need of repair.See "Related Questions" below for replacing bulbs & a discussion about the brake light switch mounted at the brake pedal.These are 2 of the most common 'fixes'.
Are you sure you need the fuse for the cruise control. My cruise control wasn't working, neither were my brake lights. All 7 bulbs were burnt out. When the brake lights were replaced the cruise control worked.
