the problem is in the connector dont worry they
only fit one way and are bayonet fitting, open the
door fully and disconnect if the pins are a blue
colour then they have corroded water is getting in so
scrape clean with a small screwdriver and reaasemble
using a silicone grease .i had the same problem but
with speaker connections if the seal is damaged
replace poss cheaper and easier to go down to your local
breakers if this is ok then check that the flexi boot
hasnt popped out of the door and the wires are chaffing
on the door structure,.<br>regards mp
