Blower fan cuts off and on at times by itself

At times the heater blower fan will shut off and come back on by itself. I have changed the relay and it still does it.

    When it is not working go under the dash and hit it with a hammer handle, if it comes back on you can rest assured the fan motor is defective.

I think the problem is with the fan.

    I am hoping that is the problem but as of now it is blowing again and the shop can not find the problem. Have had it at 3 shops now.

Heater fan runs on high all the time unless key switch is turned to off position.

Even with the mode switch in off position? The mode switch is tied into the circuit for the heater speed control switch.

Other than that, I don't know. Are you sure you replaced the right relay, the blower motor relay?

Have a 93 toyota have replaced the heater core and the blower fan and also had to replace the relay, after replacing the blower I can hear and feel the fan blowing but I barely have air coming out of the...

no. they probably cut the duct work so they could change it easier. open glovebox and if you feel lots of air in there they didnt do the heater core correctly. u may even see the plastic all broken behind glove box. they got lazy.

I have a 1992 Honda Accord. When you shut off the car the blower motor stays on and the lights on the heater panel.

Make sure your fan is wired correctly, if the fan is wired correclty which it may but could be crossed and spinning backward and sending power through ground wire causing a power up of the inside light and blower, if the wiring is good then replace the cooling fan relay, that must be shorting and back feeding power to heater control.

Fan motor keeps shutting off

I am assuming you are talking about the radiator fan

if so, then do not worry about the on time for the fan unless the engine is over heating

if however, you are talking about the blower motor fan then the concern is probably in the relay located in the harness near the HVAC case

2003 525I BMW and my battery went dead so I jumped it now my heater fan wont turn off even with my engine off and keys out

sounds like youve welded a relay shut with jumpstarting it with the heater on... check your relays - pull them out one at a time till the fan stops, you have found the relay for your heater= you can give it a knock on the ground and plug it back in to see if it frees the switch inside otherwise replace it - very cheap - stocked at bmw and good auto shops

Defroster / heater fan won't shut off /1995 Buick Le Sabre

Moe, I think you hi blower relay is bad. With this I mean the contacts in the relay are welded shut and you should replace the relay if the blower is on high all the time. Do this by removing the black plastic cover right behind the engine and removing the relay all the way to the drivers side of the relay bank. you will have to insert a small screwdriver under the relay and bend the little tang that holds the relay in place. then slide the relay out towards you and remove the green lock tab and unplug the relay from the wiring harness. if the blower finally stops then just insert a new relay in its place and reassemble in the reverse order. Good luck.

2002 explorer, heater n ac fan turns off and on

If you are talking about the inside heater a/c blower motor, it may be starting to go. You also might want to check the blower motor relay in the black junction box under the hood, usually near the battery. If this relay is cutting out, it may be bad or may be cutting out becuase the fan motor is drawing too much current due to wear.
