Like the title says; I have a 2001 F350 with No blower Motor and Just Defrost, it is actually a friends, he is building a fence, and I am looking into the truck problem. The just defrost is probably a vacuum issue, but I do not have any book for this truck, so I have no vacuum or wiring...

A friend has a 96 Bronco, the rear window is down and he has no access to the motor or regulator. Is there a way to get that window up to get at the motor/regulator assembly to remove and replace?My book said manualy close the latches (1990) and the window should go up, no luck?

That did it WOO HOO, now do I want to go cut wood or watch the Formula 1 race? 20% chance of snow, got 22 cords now, I'll Relax!Thanks to all, a $40 part, at the shop probably $80 + labor... Thanks Again.

Checked the timing numerous times, same. TPS OK Heres where it gets wierd, I do not have the BARO/MAP tester, so I unplugged the MAP connector, and the idle is great, it is responsive but the CEL is on!I think I'll risk the $40 and see if that fixes the problem.I'll let you know.

Never mind, my book calls it a B/MAP Barometric MAP

I looked at the book, shows no refrence to a MAP sensor only MAF? Is it the same thing Pressure vs. Flow?

I'll look into that also, similar idle no where near as throaty, if that makes sense. Must be your Mods

Thank You.

I was looking at the Chiltons for testing the TPS, check resistance between two terminals and compare to the chart, the chart shows voltage?Can someone clarify the test procedure....Something to be said for real shop manuals, which I have for most all the other vehicles.

Make sure you pull the spout connector???

I can try that but as bad as it is running, not sure it will be accurate

No, the tune up was done in responce to the problem, plus it was probably due for it.

If by what I have done you mean mods, it is bone stock?

Also with the TFI-IV ignition system I thought there was no adjustment The ECM took care of that?

No, but what would cause the timing to change overnight?
