Tip & How-To about Ford Expedition

Ford Expedition 1999, Climate control system, A/C blowing Hot air.

I have had my head scratched trying to figure out why my truck kept blowing out extreamly hot air and no a/c. I've done the stuff of taking apart the dash, which seems to have a billion screws you have to remove, to get to the blend door and fixed that part. Only to find I still didn't have cold air. So, I kept researching the internet and reading my Haynes book. This is when I did the smack on the forehead like "I could have had a V8" drink. OK, now for the moment....

If you have it equiped on your Ford, there is a trick to check your climate control OBD-ll system for the inside of the truck. The OBD-ll system (On Board Diagnosis). You can see if you have a problem with the area of the climate control system for the inside of your truck. You have one for the engine as well, but that is used for the pros. and is for other areas to your truck.
1. Turn on your truck.
2. Turn your heat on to desired temp. for heat. Now, do step 3.
3. Turn off your heater and A/C.
4. Press both the Floor and Off buttons together, WITHIN two seconds, release the Floor and Off button and press the Automatic button and release. Give it about 30 seconds to a minute. You should see a little single led dance on the screen where you would normally see the temp.
5. Once that time is up, you should have a number code to located your problem for the cab. If you only see it all lit up with three 888's. Then you might not have a problem. However, you just did a troubleshoot on the system and you should have normal heat and A/C coming out.

To exit:
6. To save the code press the Defrost button, then the display will turn off. To erase the information press the Blue button (A/C) then it will turn off the test display.

Note: Once you turn your heat or A/C back on you will see it is set to 75 degrees. That just means you did it correctly.
Good Luck. I hope this helps. If it does please leave me feedback.

1996 chrysler Lhs air conditioner started blowing hot air


You've probably had it fixed by now, but I doubt it is low on freon.
Unless something happened to cause a leak that quick.
My first guess would be a relay or power problem with the ac clutch on the compressor.
Most mechanics can work on brakes and ac, but some brake shops don't have the equipment to work on ac.

98 lincoln town car key switch actuator rod


Fun job. I have done hundreds of those. WHY Ford put a steel pin in that cheap piece of plastic is beyond my comprehension. However, it has kept me employed :)

Anyway, did you remove the two T-30 TORX pins that go into the tilt head? They are what the tilt head pivots on.

If you have those out and it is still not coming off of the shaft. it is probably because the bearing cone is still in there.(under the spring and clip you removed) There is a stamped-steel ring that kind-of looks like a "top hat" that the spring seats on, then under that, there is a cone ring with a split that fits down into the upper bearing. (If you don't remove these, the harder you pull up on the tilt head, the tighter the cone ring will crush into the shaft and say "FORGET YOU! I AIN'T MOVIN'!!!")
These will come up and off of the shaft with a small screwdriver or pick. Then the tilt head will come off.

Then you are only halfway there. (I hope you have the column removed from the vehicle, because you will need to if you don't.) The column has to be COMPLETELY disassembled to get that !%#$ thing in there. The shaft has to ome out of the lower housing, the ignition switch, shift tube, shiftlock actuator and all that good stuff has to come off. Once all this is removed, you must fight the little pin that the lock pawl pivots on. It is pressed into the aluminum housing and can be a real bear to get out. (putting it back in is easy) Only after the lock pawl has been removed, will you be able to slide the ignition actuator up far enough to hook the little pin into the slot that it goes in. Then you have to get it all back together.

Good luck!

this is the probleme with luxury cars ...the venting systheme works with vacum and some thime smal electris motor ...if one is broken or a hose craked ...this kind of stuff appens not much to do but to take the under dash apart and look for the problem, it could also just need a little lubrification on all the moving parts !
