Re: Renault Laguna I - Phase 2 - Heating and Cooling - Heater Fan 1,2,& 3 speed not w
fix my heater yesterday. i couldn't believe it was so easy. mine had small circuit board/resistor a small spring/wire had came unstuck. 5mins with a soldering iron. job done all working on 1 2 3 4
still thought i was going to find a thermal fuse though. hope i've done it right lol
you can see where i've marked it where should of been.hope this helps someone out.
Looks like a crude form of thermal cut-out (or fuse), wire gets hot due to excess current - heats up- melts solder - disconnects circuit. Cheaper and easier to detect than an enclosed thermal fuse.
Hope it cures the fault - but there must have been a problem in the first place for it to happen, pehaps the motor??
