Hi everyone... I have a 99 F150 with 80K miles. Yesterday, it developed two problems that might be related. 1) When I shut it off and remove the key, the heater blower keeps on blowing at whatever speed setting it was at when I shut it off. The only way to stop the blower from running is to turn the heat selector to OFF. Before this, whenever I would shut off the ignition and remove the key the blower would shut off too????? 2) At the same time that problem 1 started, the buzzer/beeper is acting up. I am talking about the beeper that beeps when you leave the lights on or the key in the ignition. At least, it sounds like that same beeper. When the truck has been parked for a long period (overnight or during the day while I am at work) the beeper will start to beep after I have driven it for about 10 minutes. It beeps about once every second for 5 or 6 beeps then pauses and does that again. It repeats this about 4 or 5 times then it shuts up for the rest of the ride. This beeper beeps very fast when I leave the lights on, a bit slower when I leave the key in the ignition and this "beep" is even slower than that. It did it last night when I started my 30 mile ride home in the dark with all the lights, heater etc. on. It did it again this morning, once again in the dark with all headlights on. As I mentioned before, once it goes through its little sequence it doesn't do it again. It also did not do it this morning after it was parked for about an hour. It seems to do it only after sitting for a long time. I don't know if these two issues are related but they did come about at the same time. Does anyone have any ideas as to what is going on???? Thank you in advance Clav Guy
