Underneath the dashboard on the drivers side. There should be a black cover which covers the fuses Interior Fuse Box Location 1999 2003 Ford Windstar 2001 Ford Windstar...

The "cause" would be a fuel system or EVAP system leak. If the fumes are that strong, then I would take the vehicle back to Ford again and make the sevice manager stick his nose in it and then tell you there is no problem....

the light sensor,take it to a ford dealer

We are having the same problem and looking for a solution. My husband is in the garage right this minute pulling things apart :0). Tried searching YouTube, but no luck. HELP!

Possible coolant leak on hot engine parts causing it to evaporate as it leaks. That would definitely invade the cabin air. You would need to carefully check under the hood with the engine warmed up and running.

Also could be a headgasket failure between coolant channels and a combustion chamber. This latter problem sometimes shows itself as vapor at the tailpipe after there should be no more visible. You may also detect the odor of coolant there too.

i have a ford windstar 1995 model,also i have a transmission problem,when is cold it drive nomal like 1000 meter,but when it hot stop driving,what do u think is the problem?

burnt or unburnt gas? if burnt gas smell look for bad manifold or manifold to pipe (donut) gasket.
if unburnt smell look for gas line leaks

Several things to check. Have the cooling system pressure checked. A quick and simple test. Puts system under pressure and helps to locate a leak. The coolant doesn't just go away, it's got to be leaking either externally or internally. Be sure that the radiator cap is checked too. It needs to maintain the proper pressure for the system
Sound like coolant is leaking on the exhaust system. This can result in the smell and you will not see a leak as it is evaporating when it hits the hot pipes.
Good Luck

If there is white smoke coming out of tail pipe, the head gasket is blown. needs to be replaced.
