Radio, dome lights, and keyless entry not working (Fuses Ok)

I guess I don't under stand your post? If everything is working, then what is the problem?

If my memory serves me, this vehicle has a Body Control Module fitted which takes care of these and many more functions. By connecting the jumper cables incorrectly, this module may have been damaged and will need to be checked and or repaired by qualified persons. The radio may also have been damaged by incorrect jumper cable connection . To be honest, incorrect cable connections can destroy most electronic devices in the blink of an eye and can be very expensive to replace damaged parts. My advice would be to take the vehicle to a qualified auto electrician and have all the vehicles systems checked including ABS brake systems, Airbag systems etc.

the keyless entry does not have a fuse itself however the vehicle has a iod, or storage fuse, that will disable the keyless system but other accessories wont function, the dome light , clock, or radio, if those items work then the fuse is good. check the remote itself, the dealer can check the remote n/c, if the remote is ok than the relay can be bad or the alarm module, best advice, take it to the dealer, they will know whats wrong with it and it wont cost too much to diag .

there is a fuse for the dome lights that has no power you need to check it for power. it shold have power all the time, it feeds the radio, dome lights, power locks, and keyless entry.

Check fuse 8 (10 amp fuse) in the under dash fuse panel. Make sure you have voltage to it on both sides of the fuse.This fuse feeds all of the items you listed.

The interior lamps system consists of 2 main features. Illuminated entry and a battery saver feature that will turn the interior lights off after 20 minutes if they are left On with all doors closed and the ignition Off. The body control module (BCM) controls both of these functions. Battery power is supplied by the BCM through CKT 1732 to the following lamps:
• The dome lamp
• The map lamps
• The rear reading lamps
• The rear dome lamp
• The cargo lamp
• The glove compartment lamp
• The courtesy lamps
• The sunshade lamps
The BCM also controls the ground circuit side of the dome lamp and reading lamps for illuminated entry. The dome lamp and reading lamp will remain on for 20 seconds after the ignition key is removed and the last door is closed. In addition, if the vehicle is equipped with remote keyless entry (RKE), the dome and reading lamps will turn On and stay on for 20 seconds after an UNLOCK signal is received from the keyless entry transmitter.
The reading lamps, dome lamp and map lamps can be turned On at any time by moving the appropriate switch to the On position.
The rear dome lamp is fed battery voltage through CKT 1732 from the BCM, through the liftgate ajar switch, and is grounded through CKT 650 to the rear ground splice pack. The rear dome lamp will turn on when the liftgate is opened. The cargo lamp is fed battery voltage through CKT 1732 from the BCM, through CKT 744 and grounded through the decklid ajar switch.
The courtesy lamps are fed battery power through CKT 1732 and are grounded through CKT 745-- left front, CKT 747--left rear, CKT 748--right rear, CKT 746--right front. These circuits will ground through the door jamb switches. The courtesy lamp will be illuminated when the affected door is opened. For example, when the right rear door is opened, the right rear door courtesy lamp will turn on.

Not a fuse problem , if the BCM had blown fuse other thing's wouldn't be working as well . . Probably wiring or BCM . Using factory diagnostic,s instead of guessing as to what the problem is , is the proper way .

Interior Lamps Diagnosis
Symptom
Procedure
Important: Before proceeding with these diagnostics, check for DTCs. If DTCs are present, complete the associated diagnostics. If the condition still exists, return to this chart.
All of the interior lamps are inoperative when any door is opened.
Chart 1
The dome lamp is inoperative in the ON position, but OK in the door position. The map lamps operate normally.
The dome lamp switch is faulty. Replace the dome lamp switch.
The dome lamp is inoperative in the DOOR position, but is OK in the ON position.
Chart 2
The dome lamp is inoperative in any position and both reading lamps are inoperative.
Disconnect the dome lamp connector (BLK 3-way).
Check for voltage at terminal "C" CKT 1732 ORN wire.
If OK, the dome/map lamp is faulty. If no voltage is present, there is an OPEN in CKT 1732.
Either the right or the left sunshade mirror lamp is inoperative.
Chart 3
Either the right or the left rear reading lamp is inoperative in the ON or the DOOR position.
Chart 4
The rear reading lamp is inoperative in the ON or the DOOR position.
Chart 5
Battery rundown protection is shorted to ground - B1482.
B1482
The left rear reading lamp is inoperative in the ON or the DOOR position.
Chart 6

GM used a ground buss under the carpet near the drivers door sill. It gets wet and corrodes causing electrical problems. You can clean it up with steel wool after disconnecting the negative battery terminal. I can't remember if it's near fuse pannel or under the drivers seat on Chevy trucks.

Thanks for the help. I repalced the 10amp fuse that controls the dome lights and the wireless lock started working ..

Did you test the fusible link?
It's a smaller gauge wire that comes off of the + terminal of the battery post.

The signal from all the door switches is fed to the factory radio. From the radio, the signal goes to the dome light. When the radio is removed, the dome light does not work since the circuit is "cut".
Fortunately, there is a very simple workaround this problem. If the car does NOT have a factory alarm/ keyless entry, all you have to do is tie two wires together.
There are two green plugs. Get to the one that is plugged into the radio (if you have both green plugs going into the radio, then you DO have a keyless entry system).
Tie together the Green/Black (at the corner of the plug) and the Green/Red (3rd pin, opposite corner, same row).
Before tying the wires together, test both wires. With the radio plugged in, both wires should get a ground when a door is open and nothing when the doors are all closed. Once you have determined that they are in fact, the correct wires, unplug the green plug from the radio. If the dome light still works, you do not have to worry about it. If it doesn't, temporarily jump with a wire both pins at the plug. If the dome light functions correctly, then you can permanently jump the wires together. The preferred way to do this is to strip some insulation on the wires, solder a jumper wire and insulate with electrical tape.
