wiring schm/ a.c. after market

for the past 3 summers, I have burnt the switch out in my a.c. The wire that goes to the high, gets so hot it melts the back of the switch. Ive added a in-line fuse, to no availe.
this is an after market unit that cools perfectly. when i read the ford manual for my van, i see a 'resistor' in the a.c. wiring? i need help on what is the proper wiring, as it will soon be in the 110 degree zone. Heeelllpppp!!

It would help to know the vehicle year, make, model and what aftermarket A/C system it has.

Some Fords have had problems with poor A/C switch pigtails. Any parts store should have a replacement which is upgraded with better and thicker wires.

You could wire in a relay just for hi to take the load off the switch.Just use heavier wire on the load side of your new circuit.

I agree with the installation of a relay..almost all Factory A/C fans use a relay for High blower setting. Without the relay you draw too much current through the switch and its not made to handle it.
