well my heater motor was playing up, sometimes it would work most of the time nothing,oh and sometimes it would work but make a nice knocking noise,so i thought i would have it out and check part numbers and stuff..while it was on the floor i thought lets spay a whole can of electrical contact cleaner in it and see what happens!!!!well....it works fine now...:yahoo:.....so much crap came out of it i spose it was just the brushes got gunked up!!!!!!so before you get a new one spray the hell out of it and see what happens!!!!!
all the best all..xxxx
