Van doors won't lock with clicker, air conditioner

Go to auto zone an test the transmitters battery

Did you lock then unlock the driver door with the key ?

I asked a frend about your problem and he said there isnt one, he said when you use the clicker, your moveing away from the car, so you get an audable sound to let you now it's working, when you use the key your at the car and you now whats happening.

is it a factory alarm or after market . both have relays and fuse to them

please go to the alarm or dealer shop to replace or re program

sounds like water in somewhere ?? but where without my head under bonnet i couldnt say ,but its soaked something so perhaps it will be ok when it dries out

If the horn fuse ( Fuse #26 ) is installed and has power on both sides of the fuse, you might want to check that the horn connector is still on the horns.

The horn relay is not serviceable in the fuse panel.

You can test the horn connector for power, the Yellow w/ Light Green wire, when the horn button is pressed.

My 1991 Lexus LS 400 does something similar. When the alarm goes off I use the key to unlock the passenger side front door and it turns the alarm off. Go figure, I know it sounds funny but it solves the problem for me.

When my alarm goes off, it usually happens when someone sticks their hand in the window to unlock the door. In order to turn off the alarm I close whichever door the person opened back, and unlock the door from the driver's side door. This usually turns the alarm off.
