The way to fix that is to go to a local auto-electrician and they will just replace the contacts in the junction box by crimping a new one to the wire, and locking it back into the junction box.

You might even be able to do it yourself by bending the contacts in the socket a little with a thin blade screwdriver.

you may have a sweet or something in the seat belt lock making the switch move out of the way, build up on it makes it move out of the way. may be able to clean out with a cocktail stick or somthing like it

use the auto lock on your keys to lock and unlock this should fix it

there are switches that control the vents on your heating system(heater core) ..these have to be checked ......is there any air at all blowing out ?no? check blower motor .....

Undo the bonnet, look to the right, are the battery leads connected? if they are, put some jump leads on it (using another car, making sure the other vehicle is running) then try and open the doors and start it.

I just replaced my battery today and noticed a switch that the battery sits on. I havent looked in to it but I would guess the car wont start or maybe even not turn over it it thinks the battery has moved from where it belongs. Hope this helps some.

Could be fuel pump. Have you changed your fuel filter?

Where is this fan located and what does it cool?
