Check the coolant level. If it's low, what you describe will happen. There is not sufficient coolant to flow through the heater core at idle. At 60mph the water pump is spinning quickly, managing to get some coolant through the heater core, so you get heat until the rpm's drop at idle. If it is due to low level, keep an eye on it to see if it drops again, as you may have a leak.

Testimonial: "Thanks for the great advice. I will try that and see what happens. Thank you again. This is a great blog for people like me."

I have a ford windstar which start but does not accelerate fully.

More infromation may be helpful. If your van runs fine at low speeds but will not run properly or shift correctly at speeds of 50 mph or better I would suspect a clogged cataletic converter. If this was helpful please leave good feedback if not please repost with more infromation

Have a 99 Ford Windstar last tuesday night my heat worked comming home but when i turned the vehicle off and went inside for and hour and came back out to drive it again the heat no longer works. It blows...

If the van didn't over heat then no. Sounds though as if you did loose coolant and got an air pocket in the system. refill and keep a check on the coolant level. If it keeps going down, then you will need to find the leak and repair it.

2005 Pontiac Montana SV6 heater blows cold when slowing to idle

How cold is it there and does your engine cool down any while going slow? If it does it may mean you need a hotter thermostat installed, My first thought would be to check the coolant level in the radiator and the coolant reservoir! Hope this helps and Merry Christmas
