hi i am new to the forum guys am wanting to know i have 2002 f150 4.6l 4x4 the heater blower sometimes cuts in and out its been happening past few days any idea of whats the prob and how to fix (( after it takes the time to run regularly it can be good for an hr or 3 or untill i restart truck again or even sometimes maybe after few starts and it happens ))
just the line art one that shows which is the flasher and which is the blower motor relay.
Turn on your turn signal, and check under the dash just to the right of it. Might have black tape on it, but you should be able to find it with the clicking of the flasher. The other relay is the blower motor relay.
juts to make sure guys the fan when its workin or when its not its happening same on all 3 speeds mostly now its not working but sometimes it trys to cut in and its really low sound like a buffer noise when its trying to work just need to know for sure whats wrong and what i need to fix ..sscully if you can help or anyone it would be appreciated
