Car Stereo unlock code for a 2000 Pontiac Monta

Did you chop up wires to install the new radio ? Is it a aftermarket radio ? You need to have some one check your work !

It appears to be that the radio clock display has malfunctioned, and is due for a replacement radio, which could be an aftermarket or oem radio, maybe found at a junk yard.

Tools required for oem replacement radio, torx keys set.

Before working on the radio or other electronics, disconnect the battery cables with 8mm wrench.

Replacing the oem radio is much easier, if you obtain oem radio, compared to aftermarket radio, due to being direct fit.

The radio is same for 1995 to 1999 Pontiac Sunfire and the Chevy Cavalier, regardless of sub models, such as SE,GT, VL,VLX,Z24. etc.

Parts needed for the the aftermarket radio install :Stereo assembly, stereo wiring harness adapter, radio antenna adapter, and dash install kit.wiring diagram for the wire colors / functions, along with tools, such as torx key set, screwdrivers,wire crimper, wire stripper, double ended wiring connectors, hair dryer.

The oem stereo removal video is for the 2000 to 2005 Sunfire / Cavalier, but are the same or very similar procedures.

It is registering, but the light is burned out. You can probably use a flashlight on it and see a faint glow of numbers, but you just need a new bulb. Your radio is probably only half lit on the readout, too. Common problem with Pontiac sunfires. Dashbulbs. Cheap fix, but time consuming.

its definitly something taking power ,have you install something new lately,car stereo,amp,if not could be just car trunk light,under hood light,stays on.things to check

There will be a fuse for you dash lights and they are just light bulbs in the back. Is it just your odometer light that went out or the whole dash cluster? In all likeliness it's probably just the bulb that burned out.

You need to get a code reader to see if there is an error.
