No, an operated fuse would permanently disable power to your radio until replaced.
Assuming someone didn't do something like spray WD-40 into the radio to fix, who knows what, (as an example), your problem sounds like a logic board issue in the radio itself. This should be diagnosed by a reputable radio repair depot and not just a stereo installation shop.

With or without memory seats ? Power Seat Inoperative (w/o Memory-A45)
Power Seat Inoperative (with Memory-A45) The driver and front passenger power seat systems each consist of the following components:
• Seat Adjuster Switch
• Seat Horizontal Motor
• Seat Front Vertical Motor
• Seat Rear Vertical Motor
• Seat Recline Motor
• MSM/LT FRT PWR SEAT Circuit Breaker 25 A
• MSM/RT FRT PWR SEAT Circuit Breaker 25 A
Seat Adjuster Switch
Battery positive voltage is supplied at all times to the driver and front passenger seat adjuster switches from their respective Circuit Breakers that are located in the rear fuse block. Both seat adjuster switches are grounded through the switch ground circuit and G 300. The seat adjuster switches provide both power and ground to the selected seat motors.
Motors
All of the seat motors operate independently of each other. Each motor contains an electronic circuit breaker (PTC) that will reset only after voltage has been removed from the motor. There are four seat position motors. These are the horizontal motor, front vertical motor, rear vertical motor, and the seat back recline motor. The horizontal motor moves the entire seat forward and rearward. Both vertical motors run simultaneously when the seat switch is operated to move the entire seat up and down. Or they can be selected independently to vertically tilt the front or rear of the seat up and down. The recline motor moves the angle seat back forward and rearward.
Do you know what a wiring diagram is , how to use a DVOM - digital volt ohmmeter to test the electrical circuits ? This is how a professional technician would go about finding the problem . Horizontal
When the seat switch is operated to move the entire seat forward, battery positive voltage is applied through the horizontal motor forward switch contacts and the horizontal motor forward control circuit to the motor. The motor is grounded through the horizontal motor rearward switch contacts and the horizontal motor rearward control circuit to the motor. The motor runs in order to drive the entire seat forward until the switch is released. Moving the entire seat rearward works similarly to moving the entire seat forward, except that battery positive voltage and ground are applied on opposite circuits causing the motor to run in the opposite direction.

Faulty coolant temperature sensor and a faulty heater control valve.

2005 Buick... | Answered 3 days ago


it's not a valve it's a blend door or blend door actuator under the dash that switches the way the air is handled in your vehicle. I would start by removing the fan motor in the passenger side foot well and make sure the fan is clear of all debris. then you should be able to switch cold to hot on the dash and hear a door change the direction of the air inside the box in your dash. if that blend door is not working properly then you will need to see if there is a blend door actuator http://www.youtube.com/watch?v=AKA3LLFreTw

If I remember correctly, it should be on the drivers inner fender in front of the left front tire under the hood. Seems like it should be hiding behind the washer bottle or the coolant reservoir.

Check the condition of the plug on your neutral safety switch or otherwise called the transmission range sensor. It is on top of your transmission where the shifter cable is connected.

The more common problem is the torque converter lockup solenoid could be intermittley disengaging. You need to have the TCM (Trans Control Module) scanned to determine cause.

The thing that burned is a fuse link. It's a wire marked "fuseable link" and it's connected to the battery stud on the starter replace it with a link of the same size you can use a regular wire to start and move it but don't drive it that way because if something grounds out the whole car will burn. If there's more than one link down there and if they don't look burned just pull on them and the one that pulls apart is the bad one, I just had a thought if there's enough of the link left you can use a wire connector to reconnect don't try to solder the link will burn. I hope this helps. Take care. If you have more questions for me use testimonial and it will show up in my email.

If u HAD electronic stability control stabilizers, replace them. Stabilizer bar is probably flipped/ bent beyond repair. Check & repair mounts too before replacement. Finalize it with a 4 wheel alignment.

So what could be the problem? Without testing we'd have no idea . Do you know how to use a DVOM - digital volt ohmmeter to test electrical circuits ,what a wiring diagram is an how to read one . We test , not guess as to what is wrong . If you don't know any of these thing's i have listed ,your best bet mite be to take it to a qualified repair shop.
