The power door locks don't work right. they don't blow the fuse,you can take the fuse out and they will work little while

You need to clarify a little . No heater , or do you mean there is no air coming from vents . This would be a heater blower motor problem . Or is there air coming from the vents but it's cold , no heat ?

Depends where the defect if. Most alarm /remote systems lock doors before the remote will activate the starter. They do splice into the car's system..do if the defect if further down line from the splice the problem will remain. Check your relays for the problem.

Question did u buy used? Have you checked that the fuse and the CIG lighter right for vehicle and 3 any after market electronics in dash. Stereo CD DVD etc? Before I answer.

I have to put number 2 fuse in to open back hatch power lock. All the other power locks work for doors without it not rearchatch. But its the horn so.... My horn blows and its not thevhorn relay in glove compartment because it blows. Its the padding that's gone in steering wheel.

Sounds Like You Have An Exposed Hot Wire Somewhere. I Would Try And Change Cig Lighter Wiring Harness. Be Sure And Check Your Aux Outlets So That There Are No Exposed Wires. They All Run On The Same Fuse Hope This Helps!!

Probably a bad actuator in one of the doors.

Disconnect as many of the door switch wiring plugs, and wiring plugs for the seats that you can. Then, drop in a fuse. If it blows, you probably have a wiring issue, not a switch issue. If it doesn't blow immediately, reconnect the doors, and seats one at a time till the fuse does blow. Once it does, you've isolated your problem to a smaller area, and can replace / rewire that component.

If you've disconnected everything, and the fuse still blows, you probably have a wiring issue that will need to be traced. You will need a multimeter that can read ohms. You'll need to isolate different parts of the circuit (probably by unplugging and or cutting a wire in that circuit unfortunately) then use the multimeter to test the ohms from that part of the circuit to NON voltage side of the fuse holder. (If you try to test ohms on a hot circuit you will likely fry your multimeter!). If the meter reads low ohms, there is your short. High ohms (infinity) means there is no circuit, and there is no short. When you hit on something of low ohms, you've isolated the problem to a smaller area, and can keep tracing that wiring back to the fuse box to find your short.

Good Luck.

You have a short Somewhere. Check inside the Door where the Harness goes into the Doors. It is the Black Flex duct that looks like a Vacuum hose.

I have a 2004 honda pilot.The passinger door and the back door behind the driver seat will not lock or unlock with remote or with door lock switch,What can I do to fix it?

when you replace the fuse try using a bigger one for instace if it takes a 20 then use a 30
