Lincoln Town Car 1990

Hello dear community. I bought a 90’s Town Car with the 302 CUI machine ( 5 ltr. with 150 hp). Unfortunately and as to be expected a few electric gimmicks do not work. Electric mirrors out of function cigarette lighter (all) out of function window lifter rear out of function. Outside temperature sensor shows some wrong values. But what I am most nervous is that the heating can not be switched off. I have already changed the heating valve, unfortunately without success. h found that no matter what position the temperature selector lever has, no current arrives at the heating valve. Is there a fuse for this? If not possibly the control panel is defective?! Where could the fuse be for this? The fuse box in the engine compartment is not responsible for this? But I haven’t found another one yet. If the control panel is defective here the next question: How can I expand it? I hope for your expert help.
