There are several things you can do. Your car has a diagnostic capability in the Control head of the A/C-Heater. This is a mixed benefit because after you trigger the diagnostic test, you would still need to know which part it is referring to and how to change it.

For this, go to the Web and type in the subject such as Your year and make of car, and climate control diagnostic sequence.

The other most common bad part is the blower motor resistor. Check the Web for photos. Some blower motors are under the hood, some are under the dash. The under hood models have wires running from the heater blower motor across the Firewall to a small protruding part. It usually has 1 electric connector and 2 mounting bolts. 90% of this part is hidden in the ductwork.

Sometimes you need to change this part, other times you can cheat and poke the part with a stick and it will resume working.

How long will it work? It is one of those goofy parts that is about as dependable used as it is new. This also means a new part can be just as unreliable. Carry a stick in your trunk to poke this part.

SOURCE: cannot locate the fuse box in a lincoln ls

On the passenger side, under the dash, on the right side if you are looking at the dash. There is another one in the trunk next to battery. There is a third one under the hood behind the right headlight.

SOURCE: 2000 lincoln ls heater not working...thermostat?

- If temp guage reads normal, the lack of heat may be due to the Heater Control Valve. Located in front of the radiator. Lower passenger side. A real bugger to replace.
- The plastic cap just over the thermostat is key in re-filling the anti freeze and bleeding air.

SOURCE: 2002 Lincoln LS horn wont work.

the problem is your clock spring. it is not that hard to change but remember to disconnect your battery and let the vehicle sit twenty minutes. there are two screws on the side of your steering wheel. take them out then you will have the chance to release the airbag connector. once you get it disconnected there are a few panels on the lowere steering column under the dash that needs to be disconnected. the last thing will be your steering wheel bolt. it is a star socket. all together it will take you less than an hour. part cost me $138. after that my horn and my cruise control worked as advertised.

AC unit is blowing both cold and warm mixing as if


Sounds to me like you've got a stuck door. One of the doors in the air ducts isn't closing/opening all the way. Possibly stuck or possibly a vacuum leak or disconnected/broken vacuum hose. Only way to know is to pull the dash apart. Sucks but gotta be done.

2005 Lincoln LS. It blows extremely hot air all the time, and is unresponsive to temperature inputs from either side of the car. It always blows hot air.


There is a very good chance the Dual Coolant Control Valve has failed. This is located at the botton right side of the engine fan shroud and has 3 heater hoses connected to it. This valve controls heater or AC temperature inside the car.

No power getting to the ac unit on a 2006 lincoln ls.


Check all  the fuse box at the battery, and the second fuse box. Look for a blown fuse from the battery getting jumped and replace. Good luck and keep me posted.

Display on climate control screen is out and i don't see any type of description on fuse panel that fits this problem. AC, heater, fan, everything else works but the display.


U must remove the climate control unit from the dash and remove the top cover of the unit, u will find a tiny twist in light bulb socket with a tiny little light bulb, this provides the backlight for the AC/heater display, u can buy the bulb at any auto parts store, couple of bucks.
