Please help... no heat....
1998 E-150 4.6L
Fan works and was blowing really hot air earlier today. For the last week or so the temp. selector would stay stuck on cold or hot and not let me select anything in between, then all of a sudden it would switch back to what the dial is set at. For example I would turn the dial down to half way, between hot and cold, but it would still pump out pure hot air. I believe its now stuck on cold and not switching back to hot air from heater core.
Any advise on how to diagnose this problem. I don't think its anything major, possibly a relay or fuse?
I live near Toronto Ontario Canada and its feezing here! Please help me get some heat in my van.
Thanks all!

the 97s' to 2003s' have issues with the blend door. some folks get it working by hitting the "white box" under the right side of the dash, others rig the door with wire for a quick fix.
try searching the van forum with just the word "blend" alot of 98s' and 99s' have had your issue. some posts have part lists and numbers, some info on redesigned replacement parts. good luck. after reading a half o' dozen threads i'll check the heat if i'm ever looking to buy any of those years.

try the other blend door fix with the nail...
if that doesn't work try this
Here's a new method on fixing your blend door if you completely broke that piece that turns the door. http://userwww.sfsu.edu/~dmf/blenddoor.htm

Thanks for the responses guys. I have the whole passenger side dash apart and sure enough the part where the blend door meets the motor is broken. tried to appoxy it back together, It only last one day. Dealer wants $850 CDN for the whole heater box assembely. 
I'm going to comb the forum for the best fix possible, thank goodness winter is almost over.
Any other suggestions are welcome

wrapping a wire around it sounds like a good idea.
ive used epoxy on all sorts of things that eventually came apart, we use superglue / locktite 454 on all our computer security locks for lab computers and after 10 years it still holds.
I only used superglue on my blend door (no wires), and its still holding on tight.
Glad people are trying my instructions

Instead of epoxy, try some JB Weld. There are different formulations, depending on your need.

Between that and a wire wrap, it should last longer than your van.
Just make sure you give it time to cure properly.

Bob,
I hadn't heard of JB Weld before. I read the descriptions your linked me to. Sounds like it adheres to ABS plastic. I believe that blender door moulding is made of ABS plastic.
I am not convinced that epoxy adheres really well to ABS. If you can comment on the adhesive abilities of these two products to ABS, I'd appreciate it.
I guess my strategy has been to "encase" things in epoxy, and it is thick enough to manage that. Still, there is room for improvement, and I appreciate the tips on superglue and JBWeld. I gave up on superglue years ago, but perhaps I should reconsider it.
"Next time" (hopefully never) my blender door breaks, I'll use something other than epoxy. And I'll keep these tips in mind for my next gluing requirement. Always looking for good glue.
