gwpug 0 Posted June 7, 2009 Hello all not really sure were to post this but im a bit confused with the fans on the car that iv just bought. When the car gets hot the fans dont kick in! I tried to 'hotwire' the temp switch on the rad which i presume is for the fans but it has 3 wires so not sure which ones to go for!!! To complicate it even more theres a multiplug which seems to go to the fans and i have no idea what each 1 does?! If anyone has any wiring diagrams or could shed some light on how these work it would be much appreciated! car is non air con if that matters.Cheers Share this post Link to post Share on other sites

I just got slim fan stuck it from inside to suck instead of blow made the loom out of old relays and fuse, connector from another 306 so you don't alter anything in the loom and it's been working fine, Share this post Link to post Share on other sites
Tom Fenton 1,526 Posted June 9, 2009 Non air con makes things easier, if you think yours is tricky you should try and get your head around the fan wiring on a GTI6 with air con, super complicated! In your case, first check all fuses are OK. Then with some lengths of wire provide a direct live and earth to each fan from the battery to test that the fans do work. After that the next thing to do is disconnect the plug from the switch on the rad. Short across pairs of terminals at a time, one pair will do nothing, one pair should run the fans in slow, the other pair should run the fans in fast. If this works, then replace the switch in the rad, they do seem to fail quite often. If the fans do work, but don't respond as above, it may be that you have a duff relay in the box behind the grille, these can be replaced for standard relays of the same type available from any decent factors.
