2006 toyota tacoma heat wont shut off

Hi do check the heater control valve and blower control module possible malfunction or faulty, Valve normally situated in engine bay . module will be found on internal heater box .

As the alternator is connected directly to the battery via the cable and the car was under water(flooded) the internals of the alternator will be corroded so a new alternator would be in order. The radio will have water in it so a new radio will be in order.. the fan motor is pprobably seized due to rust in the bearings so see if you cam move the fan manually. If it is stiff the again a new fan will be in order..

there is a TSB for a noisy blower motor and not working except on Hi, both cover under 36K miles, repair includes replacing blower motor and or resistor block and harness, judging your problem can be a bad resistor block and harness. hope it helps

check the heater inlet valve. it is located in the heater inlet hose usually near the firewall in the engine compartment. It is vacuum operated but could be stuck in the open position.

Yes, this is indictating at least 1 low tire of the 5, maybe more...Check ALL 5 tire pressures and set them to 29lbs, as per the specs and then turn your key to"ON"...then push and hold the button under the steering collumn until the light on the dash flashes 3 times, indicating that you have re-set the computer to recognize the pressure that you now have set....

Good luck.

crawl under the truck and look up..you'll see it.

Resistor blown in heater. Follow the wires from the heater motor ( in foot well ) to a plug in the ducting between the fan and main heater body in centre of car. Unplug and remove the plate , it should be held in by a couple of screws. The plate should have a couple of wire coils of which , a couple will be broken. Replace resistor and heater should work.
Happy heating Marshall

there should be only one fan and its under the hood on the passenger side firewall. it takes about 30 minutes to change and its the only motor you will see of that side,its held in by three screws and a plug.

Replace the fan motor resistor, which is located in the blower housing, (under the dash, under the glove box) to the driver side of the fan motor. Held on by 2 screws. Common problem. I change a lot of them.

if its losing water it could be a head gasket or cracked head.
