Heater problem
1999 Mercury Mountaineer V8 All Wheel Drive Automatic

Started with changing out the blend-door motor/module.

Dropped a screw into vent air chamber between blend-door and fan. Having trouble with higher temp changes and get heat out dash when "venting" outside air. What is the easiest way to get to screw? Tried going through the small white tube hole in top of chamber, but no luck.

UPDATE: found screw-still cannot retrieve-should not be the problem with temps. However, higher heat now on passenger FLOOR only. No higher temps anywhere else. Automatic Climate control system moves slowly to change directions; No audible vacuum leak in engine compartment.

NEED HELP ASAP, THE STORM IS HERE AND NOT ENOUGH HEAT FOR DEFROST! SNOW ALL NIGHT!

Also the overhead compass/computer went out(no display or digits of any kind), any suggestions?

Lets try and get the codes
Ensure in-car temperature is between 40-90 F (4-32 C).
Simultaneously depress OFF and FLOOR buttons, then press AUTOMATIC button within 2 seconds. Display will show a dashed line in the center of the display window for up to 30 seconds while test is running.
Record all DTCs displayed and let me know

I followed your instructions, waited for the tests to complete, watching closely for codes-none came up during that time- and then all the lights inside the display came on and stayed on. Waited several(3-5) minutes to watch for codes, and still nothing. Meanwhile the system was non-responsive, so I restarted the vehicle and tried the system out. It has reset the system to work perfectly! Must have been like a computer plug and play reboot after finding the new hardware. Makes sense to me!
Tried to upload a picture for you but ". Txt" is not supported. Thanks for the help- if that's all on the auto-climate system. Please let me know.

Any ideas on the oyer-head travel computer-compass-console being completely dead- no display lights, no response to any buttons at all. Map lights work, but not the compass stuff.

The electronic circuit module inside your overhead console has failed. You can only repair it by installing a good module. If you have a "Junk Yard/Auto Salvage" near your location you could possibly get one there ..the other choice would be Ebay.
You could remove your entire console and replace it or just replace the module inside.
Here are the steps to do the module replacement.

Item Part Number Description
1 " Map Lamp Switch
2 " Compass/Thermometer Display
3 " Mode Switch
4 " Garage Door Remote Button
5 " Garage Door Remote Holder Release Button

(1) To remove the overhead console unit grab the console at the largest end right around where number 5 is in the picture above. Push your fingers into the headliner material and on the outer edge of the console. "Gently" pull down to unseat the console.It is only secured by small clips. Be careful not to pull the small wires out of their connection point.

(2) Remove the screws and disconnect the electrical connector.

To install, reverse the removal procedure.

You will need to reset your compass zone. You will need to to a calibration adjustment. The information to do both is in your owners manual. If you do not have one let me know and I will get the information right to you.
Good Luck;
Rick
