Problem is most likely the water pump.Have seen several of these doing this on the 5.4L. Impeller fins were damaged on the ones that I have seen.

The direction of the air flow (dash/defrost/floor, etc) is controlled by vacuum going to the switch. There may be a vac line that didn't get connected or was damaged when they put the replacement engine in it. Check the lines on the firewall to make sure nothing is loose.

that clicking noise you hear is likely a relay in the fuse panel that needs to be replaced. the easiest way to find out which relay it is would be to put you finger on each relay as you actuate the device not working. once you locate the clicking relay replace it . to reset the computer just unhook the battery for about ten minutes. if you have an anti theft radio make sure you know the code for it and how to enter it before you unhook the battery.

Check under dash in duct system for any vacuum hoses blown off then check under the hood on the passenger side of engine compartent.If all hoses are connected then you will have to check the heater blend door actuator and the heater blend door lever for proper operation.

My 2007 Dodge Ram 1500 seems to not be pumping heat from the floor vents, only the dash and defrost vents. Could it be a problem with the blend door? if so where do i find it and what should I do. This...


Yes, it's a blend/mode door problem. Seems like it was pretty common for a few years. I've heard that Dodge has switched manufacturers for this part.

There's no easy fix for this. The dash and the hvac box have to be removed to get to the blend doors. You also have to disconnect the A/C lines and then recharge them...

Any chance you're still under warranty?

Here's a link to a website that has info and parts about the issue. (no affiliation)

OK, a vacuum controlled blend door is the problem.


REMOVAL & INSTALLATION


See Figure 1



0996b43f8020d980.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: Plenum door vacuum motors

  1. Disconnect the vacuum hose at the motor.
  2. Remove the 2 motor attaching screws.
  3. Rotate the assembly so that the slot in the bracket is parallel to the tee-shaped end of the door crank arm, and pull the motor and bracket off the crank arm.
  4. Installation is the reverse of removal.
--- Search for other vacuum motors under the dash to see if the vacuum hoses have somehow deteriorated or become detached. --- Try to look up your vehicle on autozone.com for other vacuum motors under the 'heater' section of the 'chassis electrical' section of the 'repair guide' after selecting your 1996 Ford f250 crew cab vehicle. http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f8038ebd8

I took my 2002 ford explorer for a detail yesterday. It came back with the ac not coming out of the main vents. It works on defrost but not in the front four vents. Got any ideas


Your blend door is not operating properly. The blend door directs the air where it is supposed to go based on the settings you tell it, vent, defrost, floor, etc.
