How to turn your heater core off and on in the cab.

Youve legit had a rough go with ur ac system. I got sick of working on it in my 11 model and wired the compressor to a toggle switch and unplugged the thermisters so that tye compute would continue cycling the fan. Need to get a regular psi switch to cut it out on high psi and cycle the fan as well as cycle the compressor on the low side. Ive decided to eliminate the computer controlled blowers and run 12 or 14g thru a dimmer switch as that those blower speed controllers are what really heat up. Just gotta find the time to do it.
