When I start my truck and either let it sit an run for alittle bit or get in it an go just a few minutes after a unknown buzzer goes off. It beeps four times stop about 5 sec beeps 4 more times stops beeps four more times an stops it does that about 5 time an will quit. Then a hour or so later if I haven't turn the truck off it will do it again but there is no warning light on the dash on or anything. An I just replaced the alternator not long ago
Add on one 2005 Flare side 150 to the list of mystery 4 beeps than quit then like 1 minute 3 more slow long beeps than twice more of the cycle than silent for about an hour...
Ours stopped once we filled the tank. But will see if it returns when it gets back down to 1/4 tank.
I believe that I found the answer, though I haven't had time to test my theory. The long and short of it is that the truck is telling me that I have a warning light out on the dashboard. I'm too tired to remember what one, but I do have one out, and I hope to replace it this weekend.
My uncles 06 f150 has the door ajar alarm on everytime I get into it and then start beeping and the doors closed I don't know what's wrong with it I need answers please it's aggravating and dose it repeatedly
