SOURCE: 1990 ford f150 cross over valve location

Please Help ME by Remembering to RATE ME Thank you Vrey Much !!!

This vehicle does not use an external fuel tank switching valve. A supply check valve in the fuel pump assembly opens when the outlet pressure from the energized fuel pump exceeds the opposing check valve spring force.


R E C A L L 1991
THE DUAL FUEL TANK SELECTOR VALVE MAY MALFUNCTION AND CAUSE AN OVERFILL CONDITION IN ONE OF THE FUEL TANKS, RESULTING IN AN OVERFLOW OF FUEL PAST THE FILLER CAP.
THE OVERFLOW OF FUEL PAST THE FILLER CAP CAUSES A FUEL LEAKAGE, WHICH CAN RESULT IN A FIRE WHEN EXPOSED TO A SOURCE OF IGNITION.
REPLACE THE DUAL FUEL TANK SELECTOR VALVE.
SYSTEM: FUEL TANK, AUXILIARY.
VANS AND LIGHT TRUCKS WITH DUAL FUEL TANKS PRODUCED IN THE FOLLOWING PERIODS: F150, F250, AND F350 LIGHT TRUCKS BUILT BETWEEN FEBRUARY 28, 1989 AND JULY, 1989; ECONOLINE BUILT BETWEEN FEBRUARY 28, 1989 AND FEBRUARY 11, 1991.
NOTE: FORD HAS AGREED TO RECALL THESE VEHICLES BUT PARTS ARE NOT YET AVAILABLE.PARTS WILL BE AVAILABLE IN DECEMBER 1991. YOU WILL RECEIVE A LETTER FROM FORD ADVISING YOU WHEN TO SCHEDULE AN APPOINTMENT WITH YOUR DEALER TO HAVE THE RECALL WORK PERFORMED. IN THE MEAN TIME, YOU CAN TAKE THE FOLLOWING PRECAUTIONS:FILL EACH TANK TO ONLY 1/3 FULL. IF YOUR VEHICLE LEAKS FUEL OR IF YOU SMELL FUEL, STOP USING THE VEHICLE AND CALL FORD AT (313) 446-4654 AND ADVISE THEM OF YOUR PROBLEM. REFER TO FORD SAFETY RECALL NUMBER 91S39.

SOURCE: Heater fan only works on high speed 4.

sounds like the switch is bad. Test the power coming in to the connector and use jumpers to get the fan to operate at all 4 speeds. if it works then it the switch.

SOURCE: location of the heater control valve

There are 2 hoses going through the firewall from the engine, these are the coolant hoses to the heater core, one is 3/4" and one 5/8", the control valve should be in the larger line (3/4") which is the inlet, make sure that the valve has vacuum (heater on low), also check and see if both hoses get hot with the heater blower on low, if they do get hot your problem is not the heater control valve but the air temp control blend door actuator.

SOURCE: 1997 F150 heater problem

your problem is caused by the air temperature control blend door actuator motor being defective, the little motor moves the door that gives either hot air or cold air or a blend of the 2.

No heat 98 ford f150


verify heat is in normal range using dash gauge. if its normal then good. if it is below normal, you may have a sticking open thermostat not allowing heat to build up enough for "hot" heat. but usually luke warm heat will be this issue.

If everything is fine with gauge heat, check the hoses going to your heater core with your hands. they BOTH should be hot. If one is hot and another is warm then you have heater core issues. If both are HOT then you may want to check your temp controls. either temp control may not be working or the door that changes temp may be stuck in the cold position... there are many things, but checking the heater core hoses are most likely going to reveal bad heater core.

You will need wiring diagrams and volt meter to diagnose anything other than touching hoses and looking at gauge.

2004 santa se 2.4L Temp gauge reads normal, but heat from vents excesivlly hot.will not start after running for a while until it sits 1/2 hr.


There is a blower control resistor (manual system) or a blower transistor (automatic temp system) located behind the glove compartment in the HVAC box and this is a high failure item.

2006 chevy silverado 2500hd truck heats up to operating temp while in parking lot blower works well but truck will not blow any hot air until truck is driving at at least 15 to 20 mph. fuses good think...


If I understand you correctly, your temp gauge shows correct operating temperature, your blower fan blows air that you can feel with your hand from the right floor or dash outlet, but that air doesn't feel warm until you are moving?

If so, several possibilities come to mind. One is that your coolant level is low. Even though your temp gauge reads in the right range, the coolant level could be low enough that it doesn't reach the heater core until there is enough engine RPM to create more pressure from the water pump and force what coolant is there toward the heater core. Another possibility is that your heater controls are not able to do their job. A stuck flapper in the duct or a malfunction with the temperature control system could be causing the problem, and at 15-20 MPH there is enough air coming through the outside air vents to provide some heat.

I'd check the coolant level first, though. The other possibilities are more far-fetched.

No heat coming from heat vents, blower works. i have change thermostat still no heat


Make sure the cooling system is full ... they can run with low coolant and not have it show on the temp gauge. Make sure the heater temp control actual opens the valve the controls the flow of coolant to the heater.

Getting no heat but hoses are hot /temp gauge up half way/1997 jetta


There should be a heater control valve connected in the heater hose line at some point. Make sure the valve still works. Most are controled by vacuum.

No heat. gauge working. fairly new thermostat. replaced engine, radiator cap.?


I am guessing that the gauge is showing normal operating temp, if so, I am also guessing that the blower motor is pushing air through the ducts.... if so than

were heater hoses reconnected ?
was hot water valve vacuum line reconnected ?
was all air purged from entire cooling system after engine repplaced ?
were heater hoses connected properly to get correct direction of flow ?
are hoses to heater core under hood getting hot ?

is the heater core clogged ?

2001 ford taurus heater only bows cold air-no heat at all=ac works great tho


check coolant level in overflow bottle and the radiator first.

check to see if temp blend door is rotating back and forth. Rotate temp knob while watching the motor that operates the blend door under the dash.

check to see if both heater hoses are hot where they go into the cowl in the engine compartment into the heater core. If not hot, check temp gauge to see if it reads nomal, if not replace thermostat.

Heater and overdrive button as well as heated seats quit working


Your heater problem could be a blower motor resistor if the motor does not work at all. If the blower does work then the problem could be a bad heater valve. I assume that the 30 amp blower fuse is good. The seats and overdrive light have no connection with the blower. Does the heated seat light come on? Do you have automatic temp control.
