It was restricted and tried to go down, and ground to a halt as it was rubbing something, then it cut out. Now its stuck half way. 
I am guessing its blown a fuse, but i have wired it to run off the hazzard lights button power lead, so it doesnt go to the fuse box!? The hazard lights still work fine. The reason i was 'playing' with it is because the radio was cutting in and out, anybody know what that could be, i wiggled the connectiones etc. The relay on it seemed to make it cut in and out when i moved it a bit. Recon the relays gone?!Any help would be great, Thanks very much,
Paul

Thanks. I will need to find a new relay then. It seems to have a lot of wires going into it, so quite specific i think. Might try the stealers.
