NOW every time I open my rear doors, the taillights fuse gets blown, no lights in my instrument cluster, unless I put a new fuse.

I agree with ZX. I don't think yours is the typical door ajar light problem, Take a look at the headlight switch. The taillight flaming would be my clue. I would also check your trailer wiring at the back of the truck. May be a chaffed wire of some sort or a bad ground back there. It may be a wild goose chase but I would look into it.
As far as the typical door ajar light or dome light staying on problem, it is very common on Explorers and Rangers dating back to the early 90's. From what I have seen the problem is more common on vehicles that are driven with the window(s) open, particularly with smokers who may keep the windows cracked when it's raining. Water gets inside the door and corrodes the switch. I suspect it also occurs over time as the window seals begin to degrade. Anyway, a good maintenance item on these trucks is to treat the door latches when changing oil.

Same thing with my truck, 2001 F-350, 4X4, also started happening with my cousins 2003 F-250. Definately the drivers door, after about a mile or two of driving if goes away. I will try the contact cleaner in the door jam then post the results. Hope it works......

Well I spend 5 hours over the weekend, still could not find the problem, switches checked out ok, VSM is ok, some reason one of the back door switch cable causes taillight fuse to blow, it is very hard to trace those cables and it was getting dark I just unplugged backdoor jam switches and took the dome lights off, least now I have my taillights working and started getting used to driving with door ajar light on.

Man that sounds like it is a tuff one..Do you feel your light switch is OK? If it is not the switch, it would seem that it would have to be related to the light switch since it only blows the fuse with taillights are on..?? Have you ruled out the aftermarke alarm. Since most alarms are tied into the interior lights and also flash the taillights it may be the problem. If you haven't already done it, you may want to totally disconnect the alarm and try that.

Another thing to check is were the wires go into the door. They are always moving when you open and close the door and perhaps one or more is chaffed. The fuse may only blow with parking lamps on, because the power window switch is illuminated when the lamps are turned on.
