While I was fixing indecisive heater control servo in a Toyota Ist, I discovered a wiring horror left a by a wire-twisting moron:
In my opinion wire twisting from above is lazy, stupid, and dangerous! Unless, of course you want to set your car on fire. They didn’t even bother to properly apply insulation tape.
The Fix.
Untangling the mess:
Cutting off the twists:
Feeding in supporting heat-shrink:
Splicing the wires properly before soldering (a variant of Lineman’s splice, give it a gentle tug after twisting):
Soldering the wires (just enough of solder, do not “blob”):
Heat-shrink:
Loop and heat-shrink unused wires:
End result:
i cant thank you enough Sergi, ive had so much trouble trying to find out the problem of my heater not
working. I may not be able to fix the problem myself but I can at least give the mechanic some advise or show him your site for advice and maybe save me some money in the long run Thank you so much.
