2003 no power to radio

Yes the battery can be effected (drain) but in any kind of weather, unless you turn the radio off when you turn the engine off. The power wire in either application is connected directly to the battery as opposed to being connected to the ACC terminal which will be switched on and off with the ignition. You should connect the power wire (should be RED in color) from the radio plug to the terminal (marked "acc") on your fuse box located somewhere under your dash board. It sounds as though it's possible that the RED power wire and the YELLOW "Memory" wire have been switched, the power wire should be switched with the ignition and the Memory wire should be connected directly to a Battery terminal (marked as Batt also on the fuse box) or to the battery itself. All of these wires should be labeled with a small tab indicating there connection. Example Red wire marked (+ poss power), Black wire (- Neg Ground) Yellow wire (Memory) and usually 2 Green, 2Grey, 2 Blue, 2Purple as for the Speakers Poss. & Neg. respectively.

poor gaz flash point, spark plug,tps sensor out of range,MAP or MAF defect no code.

Okay, First you go and check the RADIO fuse in the underside of the hood. If the Fuse is blown then you have to replace it. If its not then to reset the power door , you have to take out the fuse for 30 sec. then replace and start vehicle then try to open it. Good luck, with them chevy ventures. we had one and we had to replace radiator and Head for $1200 and new window motors twice and switches.

Take your registration and go to GM dealer with the code on the radio's chasis, they will give you the unlock.

No more fuses,General Motors had alot fo problems with power window motors I personally have replaced hundreds of these in all there models over the years.Sometimes if you tap on the motor with the door panel off while depressing the switch the motor will move again for a while but it will need to be replaced. Just make sure you have switching voltage and ground at the motor connector with the switch depressed.Good luck

Transmission SPEED SENSOR

It sounds as though one of the proximity sensors is faulty. Also try giving the tracks for the door a good shot of white spray lithium grease. The door may be binding enough so that the emergency reverse is kicking in.

open the door and look on the side of door for little switch up and down ,it a safety switch ,little gray lever sticking out on the side of doors, move it up or down ,read decal on the door jam,hope to help robert b.

It is possible that it is the fuse but if so something caused the fuse to blow. It may be in the wiring which if you pull up the carpet by removing the door floor trim and lifting the carpet you will see the wiring underneath. Probably laying in water. Look for splices in the wiring which will have corroded. Repair the wiring then replace the fuse.
Another problem may be in the motors found inside the doors. The brushes may have worn out. If so you need to replace the motors. Unlikely that both motors failed at the same time though.
Usually the drivers door first since it is the most used.

the dealer is fulla **** sorry ,the radio is locked but not tied with the vin
and if u take your battery lead off then put back on it will ask you for the code and same if u take it out
the way to get the code is in your manual for the car
or ring the company who made the radio
so what the dealer is saying if it cant be unlocked when u replace the battery it will need a code what do u do ? of course u can unlock it
just do what i said above and u will have your code usaually 4 or 5 digits
