1993 Mercury Tracer/Escort heater problem?
Recently, I turned on my 1993 Mercury Tracer and after about five seconds of heat, the heat stopped coming out of the vents.
The first thing I checked was the driver’s seat fuse box and sure enough, on the fuse box cover schematic, there is a location for the 30A heater fuse, but when I look at the actual fuse box, there is no such fuse in the area it denotes.
On the schematic there are 4 rows with 5 columns on the bottom three rows. the top row only has one fuse which is all the way on the right and is the heater fuse but there is no top row in the actual fuse box.
I have checked the engine fuse box and there is no heater fuse in there. I also thought that the problem might be the heater motor but the fact that there is actually a heater fuse is puzzling. Does anybody have any insight to this problem?

OK, I don’t think its a fuse problem reason being if it was a fuse you would have nothing period. If you look closely at the fuse box under your seat you will notice that if you look at where the 30amp fuse should go that there are no electrical contacts for it to hook up to, the hole for the fuse is there but no connection so to speak. This is because your fuse box is the same one used on other vehicles type and models. You might want to check your Heater Resister Switch which is located on the Heater Blower Box under the dash on the passenger side. It should have a small pigtail hooked to it and held in place by 2 screws, take it out, the coil could be burnt in half if so this is about a $15.00 part. If its not burnt as far as you can tell check it for continuity(ohm meter)
when you say the heat stops coming out of the vents, do you mean actual hot air, or any air period?
if the fans are coming on and its blowing cool air, there could be an issue in the cooling system in your vehicle.
if the fans are not working period, it can be anything from the control head, to a blower motor resistor, to an actual bad blower motor, to a wiring problem.
