A/C Amplifier circuit board
So I have owned my 86 Pickup 22 years and 12 years ago I put in a A/C system from a 4runner model similar years. Everything has worked OK for several years then I blew a head gasket.
It seemed that after a year trying to figure out what is going on I figured out my A/C Amplifier was stuck on so the evaporator would freeze up. It seems that the condenser may go into
a superheating mode that might raise the radiator temp significantly. I have not been able to test out this theory because I can't get an identical A/C Amplifier for it. So I noticed
no new A/C amplifiers available for many makes and models of Toyota's. So I have designed a replacement circuit that could work for many makes and models. Is anybody doing this already?
Is anyone interested? I am willing to publish the circuits for the DIY person and might be willing to offer a built one or at least the circuit board. In the testing phase right now.
Just looking for encouragement. Love my 86.
