After market stereo won't power-up in 2002 Pontiac Montana

I have a Pontiac Montana 2002 and I am trying to replace OEM radio/CD unit with an aftermarket compatible one. I connected the speakers, ground and power wires but the new radio does not even power up. What happen? Does it have anything to do with THEFTLOCK feature, or would that simply lock the radio, but will not cut the power. A bit lost.

    The stereo simply does not turn on at all. The old one worked just fine. So if there's a chance there's no power coming in, what might've happen? I checked the fuse and it looks fine. How would I check if there is powere coming through this wire and if not, how would I determin where it's cut off?

SOURCE: Stereo wiring on mk4 golf r32? Fitted new stereo

12 volt accessory or same wire that goes to red wire on stereo or cigarette lighter.
OR
What is the current draw on amplified aerial ? or are you talking bout electric aerial(up and down automatically ?) If current draw is really low like 500 milliamp or so then hook her up to blue wire (remote output) on back of stereo but REMEMBER this is LOW current and only meant to switch on amps and raise electric aerials etc.If you think amp on aerial is too much for it then run the rem wire to a 12 volt relay and wire it so that when rem triggers and closes the gate will be connecting an accessory wire OR perm 12v wire to aerial power . That way aerial ONLY turns on(POWERS UP) when stereo is on as opposed to other way where aerial will be powered up every time car ign or acc is turned on regardless of whether the stereo is on or not.

SOURCE: I switched out my radio

Hello... sorry to hear you are having a problem. The theftlock system does not pertain to anything aftermarket that you do. The theftlock only locks down the factory radio if it is removed, and only if it was activated before it was removed. There was a red led light on the radio. With the vehicle turned off, if the light on the radio flashed, then it was activated. If you hook the factory radio back up then you will have to enter the code to unlock it. Since you used a wire harness adapter, check the red wire and make sure you have 12v current on that line. You didnt state if the radio powers up with no sound or if it doesnt power up at all. If it powers up with no sound, then check to make sure that the blue/white wire is hooked to the blue wire on the adapter harness. Let me know if you are having no sound or no power and I can help you further with this problem.

I installed a dual Bluetooth stereo system in my 2002 pontiac montana I installed the radio pro 5 I have it all hooked up correctly everything turned on but no sound at all what else could it be?


Depends on the type of OEM radio you had in the system before the replacement. Your car may have an auxiliary amplifier between the radio and the speakers, and if so, you may have to bypass it. In any case, have a look at the original wiring diagram (Alldatadiy.com will probably help) and check your wiring again.

Needs repair. You can pull and ship to united radio for repair or have the dealer do it. Other choice is to replace the unit with an aftermarket or salvage unit. Salvage unit may have to be programmed for tou vehicle to work right.

99 MONTANA RADIO SUDDENLY VOLUMN GETS LOUD HOW DO I MAKE IT STOP


It could be a dirty control. I'd try some electronic contact cleaner. Spray it on the volume control to see if it helps.

It could also be a broken wire that occasionally makes contact with something it's not supposed to.

How do I fix the clock display on my 1999 Pontiac Sunfire?


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.

Light burned out on radio/clock dial - how to fix?


Sorry there is no quick fix for this problem. If it's the face plate that light's up, there are some electronic shops that can fix it for under the cost of a new after market radio. Just keep in mind there the junk yard has lot's OEM radio's waiting to be bought.
