Escort van 55 blower heater does not blow at all

likely your blower motor. but take connector off at blower, key on, htr on high. should have power at connector. check with a test light. If power is present, its your blower. If no power, and fuse is good, it's a wiring issue or your heater blower switch on the dash.

common cause is, baby has stuffed a sweety wrapper in *** lighter causing short,try disconnecting each in turn until fuse dont blow...thimples.....

the resistor should be mounted on the same heater box as the blower motor

THE HEATER CONTROL VALVE MAY BE BAD OR A VACCUM HOSE OFF OR LEAKING SOMEWHERE

All auto fans run on 12-16volts. That voltage should be whatever the cars battery/alternator voltage is at the time. If not working and your blower is checked out as good you more then likely have a bad blower resistor which controls the speeds of the blower. You can verify by pulling the harness to blower and applying 12volts directly to the motor and if it comes on your most likely cause is the resistor

Disconnect blower motor & try another fuse....if it don't blow fuse then blower motor shorting out..

try putting a 12v feed to the heater fan, if it works, you have a problem with your wiring, if it doesnt work, your blower is faulty.

hope this helps.

hiya if you warm engine up to normal temp then check / feel the two heater hoses from engine up to the point of passing into the bulkhead ? if one hose is hot/warm? and the other is cold? the cold hose is the return from heater matrix(radiator) the problem you have is probably the heater coolant control valve failed? this is electric operated and not servicable but easy diy job to renew tou will find the plastic valve on the rear of bulknead behind where h/hoses pass thro you will have to remove the plastic grill below w/screen the h/hoses are connected to the valve along with elec plug connection pull off plug then with ignition and temp control valve on max check you have a live feed on wires to valve ? if no? check fuses if yes? then replace valve hope this helps it is not uncommon fault with these valves on escorts and fiestas

I take it the water level in the expansion tank is ok. You could have a blocked core in the heater. Also the heater could be leaking. You could try flushing the cooling system and checking for leaks and blockages.
