do you have the manual heater control or the optional electronic. also the service manual could be very handy to help you

Clutch on compressor running good. What is the ohm's I should get on the relay coil? I removed the relay off its shell and closed the relay points with a piece of small paper. Since I do have volts on the relay coil, jumping the E and A points makes the A/c run, cooling good. The problem is E and A wont close by itself. Any ideas?
