Ok, I have a 94 nissan sentra. When I have the lights on, The rear mid brake light and passenger side rear brake light remain on at all times. Driver side rear light seems to work properly. Now, when lights are off and I then depress the brake, the interior lights, as well as the fog lamps in front of car flash on. When I let go of brake, the lights go out. Very confusing. Need help. Thanks.

SOURCE: abs on dashboard stays lit all the time.

The only way to know axactly what happen is with a diagnostic computer.
Because the ABS use a Speed sensor on each of the wheels.
Hydraulic selenoids on the ABS box or Module..
If the light is on. its mean the Anti Lock Brake System is inactive., You gonna brake like any car with no ABS.
I hope this information work for you.

SOURCE: installing a Nissan Sentra Passenger Side Manual Non Folding Mirror.

had to install a driver side non folding mirror, fairly simply to say the least. There's a cover on the interior of the door, near the window, remove the cover, remove the 3 screws, need i believe a 10mm socket. If a power window, unhook the circuit. Replace new mirror.

Transmission shift indicator light on center console.
First make sure the fuse is good.
If the fuse is good then remove the screws holding the center console cover. You will need a long and short phillip screwdriver. Look for screws in the cup holder, under the handbrake handle and where the console runs under the dash. You may have to move seats forward/backward to reach the screws. When you attempt to raise the console cover you will notice you overlook a screws. Remove them also. You may be able to reach the bulb without removing the gear shift handle. DO NOT TOUCH any other electronics you see. The AIRBAG ACTUATOR is located here also. Replace bulb. Test before reassembly. Good Saturday morning project.
