How to Check the Encoder & Limit Switch

1) Inspect suspect window slide mechanism. Ensure slide is free from debris or damage. Check for worn molding. Ensure window is not binding in the molding.  Repair as needed. If window is able to slide freely, go to next step.

2) Disconnect suspect window regulator connector. Access power window switch harness connector. Do not disconnect connector. Turn ignition on.  Back-probe connector, measure voltage between ground and terminal No. 9. If voltage is present, go to next step.  If 5 volts is NOT present, replace window switch.

3) Connect suspect window regulator connector. Ensure window is fully open. Access power window switch harness connector. Do not disconnect connector. Turn ignition on. Back-probe connector, Measure voltage between ground and terminal No. 9. Raise window while monitoring voltage. Voltage should remain at zero volts until window is within .59″ (15mm) of being closed. Once window opening is less than .59″ (15mm), voltage should be 5 volts. If voltage is as specified, go to step 5. If voltage is not as specified, go to next step

4) Reset suspect window limit switch (located on window motor). Fully close window. Press and hold reset switch on window regulator. Fully lower window. Release reset switch. Fully close window. Repeat step 3 at least 10 times. If voltage is as specified, go to next step. If voltage is not as specified, replace window regulator motor.

5) Further testing will require using an oscilloscope. Turn ignition on. Backprobe suspect window switch connector, measure voltage between ground and terminal No. 9. Raise widow using automatic function Square wave pattern should oscillate between zero to 5 volts. If oscilloscope pattern is as specified, replace power window switch. If oscilloscope pattern is not as specified, replace window regulator motor.


Dual Temperature Control, Automatic Temperature Control (ATC) or also called Electronic Climate Control not working correctly. Mode selection not working or the lose of the ability to switch airflow, which defaults to the defrost setting.

Today’s Vehicle Electronics are becoming very High-tech with the addition of many new creature comforts. One such feature is Dual Temperature Control, Automatic Temperature Control (ATC) or also called Electronic Climate Control. This feature allows the ability of adjusting different temperatures and fan speeds for the driver and passengers. Another word associated with temperature controls is  HVAC (heating, ventilation, and air conditioning) which refers to technology of indoor or automotive environmental comfort. Most common failure complaints with ATC systems is the mode selection fails or loses it’s ability to switch airflow which defaults to the defrost setting. This system is very complex, with a specified procedure to determine the particular conditions present. This should be diagnosed by a Certified Automotive Technician and requires the use of a scan tool to check for set DTC’s which may affect HVAC operations when present.

Dorman Products now offers a line of remanufatured Climate Control Modules. Dorman has recognized a few failures and improved these problems of the climate control modules.
With all modules one failure that was redesigned is in the mode selection, which results in the lose of ability to switch airflow and defaults to the defrost setting.
On models 599-030, 599-001 and 599-003 the lamp failures have be addressed.
Model 599-030 a revise to the back-lighting has been done along with a update to the deterioration of o-rings. These Remanufactured climate control modules are fully tested, and are plug and play ready for easy installation with No Programming Required.

TO INSURE CORRECT ORDERING  OF AUTOMATIC TEMPERATURE CONTROL MODULES YOU SHOULD MATCH-UP THE OEM PART NUMBER. TO OBTAIN A FACTORY PART NUMBER, HAVE THE  VIN NUMBER ON HAND AND GIVE YOUR LOCAL DEALERSHIP PARTS DEPARTMENT A CALL FOR THE FACTORY PART NUMBER YOU ARE REPLACING.

2003-2005 Ford Crown Victoria and Mercury Grand Marquis, Headlights dropping out while driving due to the Lighting Control Module (LCM)

TechSmart Lighting Control Module  (LCM)


The LCM is Fords answer to problems with electronic interference and excessive heat with thermoelectric devices used previously.
The LCM is a microprocessor based module that controls several exterior lighting systems.
System include headlamps with auto-lamps (if equipped), turn-signals/hazards, corning lamps, parking lamps and battery saver.

Most common problem with the Lighting control module is that the headlights stop working for short periods of time while driving. Due to the relay in the control module over-heating. Ford recommends only using headlight bulbs that meet there specifications, as this may cause or contribute to this condition.

Ford headlamp bulb specifications – Bulb part # 9007
-low beam light should be rated at 4.30 amps @ 55 watts,
-high beam should be rated at 5.08 amps @ 65 watts.

Before replacing the LCM, make sure all fuses and relays for the exterior lights are good. Refer to you owners manual for fuse/relay locations.
Where is the LCM located? The Lighting Control Module (LCM) would be located, behind center lower of dashboard.
