fan blows cold air

[magnus]

Hi guys,

I have brought my truck in twice to the Ford dealer, and they claim "it´s fixed, see ya" each time.

Here is the issue:
- The truck takes a long time to get warm. Once it´s warmed up, the fan keeps blowing cold air inside the cabin, even though the heat needle shows it´s warm. I have also notice that the needle was at 1/2 like when it´s normal, but then dropped right down for a minute. It does blow warm air from time to time though. When I brought it in, the added antifreeze, and that seemed to have fixed it, and worked fine for a while, until now. I have not checked the antifreeze level though.
- another problem I noticed few days ago that the turbo is making a weird noise sometimes, like a dog crying noice if you know what I mean, but goes away of course once I let go of the throttle, any ideas?

thanks!!!

forgot one thing that I am just curious about. How hard is it to change the injectors yourself on those trucks? Do you have to remove the cab? Do you know what the labor is in hours?

As far as the air blowing in the cab are you talking about the Air Conditioning out of the vents BTW I like the Prodigy phrase on your signature

hi, thanks

I´m talking about the fan that warms the cabin up, dunno what it´s called other than just a fan but yeah, even if I crank the heat right up, it blows nuttin but cold air.

Alright..... It could be a couple of things..... First open the hood of your truck.
If you are looking under the hood from the front of your truck look torward the left to the rear of the engine compartment you should see 2 black hoses going into the firewall. One of them above the valve cover has a vacuum valve that opens and closes whenever you turn the heat on and it should have a gray hose hooked up to it. Make sure thats working... If it is then your Blendor Motor has went out and thats way up in the dash. I hope its simple enough for the vacuum hose falling off or a vacuum leak under the hood. Hope this helps you

I had the same problem in mine.It was from the coolant level being to low from my head gaskets blowing by. had head gaskets done and havent had a problem with it since. I was having to add about a gallon of coolant everyday.

I'm can't remember if this was in the 97 obs or my 01 but sevral years ago this same thing happened to me, seems like it was my 01.
Anyhow a ballpoint pen fell down inside the passenger side defroster vent and block a door in the ducting,...can't remember if it kept the door from closing or opening. Once removed everything went back to normal.

Froze my butt off and it drove me nutz till I found it.

Hope that helps,......Iceland?....Brrrrrrrrabbit

Sounds like there is air in it, make sure its full of coolant, bleed if necessary. Also feel both heater hoses they should feel about the same. If one is warmer suspect a restricted heater core.
