hey, im in school right now, and I have been thinking about a few questions that I have and hoping that someone can answer them.
have a 74, 1.8l yesterday I installed my heating, which consistes of a flapper box on the drier side, which is wired open, and a tube going from the heater channels, to the longs. now, i drove it yesterday and the heat kinda worked, i got defogger, but the blower that is next to the steering wheel, is not working. i turn the fan on and it kinda puts out cool air, but no heat. also, i know that there is something wrong with the wiring because when i pull the heat lever up by the shifter, the fan in the engine bay does not go on. so today i will work on that when i get out of school. but what confounds me is this. when i put the fan lever on the dashboard all the way to the right, it interfears with the radio. the radio flixers on and off. does anyone know the exact wiring of what is suppose to be underneath the dashboard on the heat levers? because I think that there is something not right underneath there. also, when I was driving to school this morning, i noticed somthing that caused me to get concerend greatly. I started the car, and then waited for it to heat up for a couple of minutes. then when i was driving, i noticed that the fuel gague was skipping around. from empty to half full, to empty. and also, the tackometer dosnt seem to be working, but the speedometer dose. AND the tripometer dosnt work right, although the odometer seems to be working correctly. if you have any suggestions on what I can do, it would be greatly appriated. -rocket |

the fan in the fresh air box does not provide heat. decifer the controls. 2 top levers all the way to the right lets in COLD air. notice the blue tapered symbol. the lever(red knob) on the bottom controls warm/hot air out the windshild or underdash vents. you must take out the 2 bolts that retain the lever on the floor, and make sure that the green wire is connected to the tab on the lever, it provides the ground for the aux heat fan located in the engine compartment. you need to check the fuse and the round relay on the relay board (in the engine compartment! not under the dash). does your aux heat fan (the one in the engine compartment) work properly, run? are the hoses from the fan to the j-tubes in place? if not you must cap the j-tubes. unless you have late (75-76) heat exchangers, you should have 2 heat/flapper valves and 2 hoses to the tubes on the firewall. take some pictures and post them in this thread so we can see what you are doing and what you have.
