My battery dies with the engine off in my 2001 F-150. At one point the fan that blows into the cab would run with the engine off. What could be the problem?

This sounds like an issue some 97-03 MY F-150s have, where a windshield ( or roof panel ) leak down into the area by the Cab fuse panel, and soak the GEM ( Generic Electronic Module ), causing all sorts of strange problems.

Depending on how long this has been happening, resealing ( or replacing if bad enough ) the windshield is in order, and dry out of the dash area with a small space heater can cure the issue.

If this has been happening too long the GEM to Cab fuse panel ( it is bolted to the back of the cab fuse panel ) connector pins can be discolored / corroded and the fuse panel / GEM needs to be removed and the pins cleaned ( hard to do on the female connector ).

Here is the manual section on GEM removal for the 1997, the process is very similar on the '02 MY F-150

I turn my car off, pull the key out, and the fans keep running until battery dies. How can I fix this?


How hot does the engine get in degrees F? Any applicable trouble codes? For radiator fan, have to check wiring diagram for your fan controls. Might be an issue with fan relay? Usually the coolant temp sensor has some control over the fan. Don't replace anything unless your testing points in that direction.

1995 Geo Prizm. A/C works and is properly charged but fan won't turn on. also speedometer doesn't work and longer.. any correlation?


blower fan in dash.
fan on RAD
fan in front of ac condenser in front of car.
does the fan in dash blow , on high?????????
does it? if not say so.

the car is Corolla,
and same car.
and works same.
when the Blower dies, in the dash , the A/C will be cut off fast.(but not if blower is dead)
this is normal for blower dead. (power to it, dead )
this is to prevent icing up of the evap core (might crack it)
SPEEDO SIDE TRACKED:
are both speedo and odom are dead?
why not say so/?


26232154-4g1iytzfkimywqjfw30jhjyb-3-0.jpg rule 2, if the dash blower blows on high , its not the resistor block
proof.
below.

on high the resistor block is bypassed,
if blower works and that center fuse below blows, the AC goes dead because 12v dont make it to the the clutch relay.
if top fuse below blows, a./c and blower die. even on high.

you can see all this stuff on mitchell's, if you want. as most do.


btw , the a/c compressor may work , if the the blower has power, but the blower is burned out.
the A/C amp logic module sees the 12vdc leaving the switch and assumes the blower works.
this rule on blower on, is to keep the core from icing over, and that can bend things.
that resistor block is air cooled, and is on the fan chamber to get cooled that way, if not it burns up.
but why not tell us if the fan works on high.
that way we save 90% of all BS guessing.
why not?

first is fuses.
then if fan blows on high only, then the fan is ok and the resistor block is bad.
if blower dead on high, the blower is bad,
the fuse blown or the wires to it are bad or the switch,
what a tech does is use his voltmeter, a $10 tool.
if you have 12vdc to the motor then the fan is history, dead.
if not, 12vdc there, fan on, then you work them meter backwards until you find the open circuit.
really its that simple.
if confused ask quesitions.
if you cant test the fan on high, tell why?

I don't know model year? Is the radiator fan electric or belt driven? If electric look for electrical connector. Your water pump has to be driven by something. If fan is belt driven, some makes and models, that same belt drives the water pump.

The fuel pressure sounds too low. Is it multi-port injection? Check the fuel pressure against your specs for the car and engine. MPFI systems usually require 40-50 psi.

Is it possible that with a battery that is loosing its charge that it could affect the heat? It is a 2005 Highlander. Thanks!


No, the battery has nothin to do with heat inside the cab. The heater works from the hot water in the engine (actually a mixture of water and antifreeze) This coolant mixture runs thurogh the engine to keep it around 190 degrees. It also runs through a small radiator (called a heater core) under the dash. there is a fan that blows air acroos the heater core and viola' heat in the car. Can you believe this used to be an option! Anyway, you bateery has nothin to do with heat. In the winter, a stuck open thermostat can cause you to have no heat in the car.

Cooling fan running after engine shuts off even with engine temperature at normal it continued to run for over an hour after driving


Someone hard wired it directly to a constant power source. I assume there was a problem with the fan at one point for someone to do this. If you disconnect the power wire to the fan and jump it to one of the fuses that only has power when the vehicle is running you will solve your problem. I would think your battery would be dying running for over an hour after the car is off.

2005 Chrysler Sebring Sedan Fan continues to run


Hi !
A little bit confusing.... though interesting...
when the fan noise is coming please open the hood and physically see if the fan is working.....
What I see is that the thermostat connected to the fan needs to be replaced.
BUT first see physically if the fan IS making the said noise.
Regards
Berry

Supperduty is blowing cold air at low speeds but heat works when engine is under torque...also the engine cooling fan will also run in the winter.


Check your coolant (antifreeze/water) level. If it's low, that's your problem. It might me a clogged heater core also. Hopefully just low on water. The fan should run year-round. Otherwise there's a risk of overheating, even in the winter. Good luck.
