The shift on the fly switch is not powered like other items, it is a signal sent through resistors back to the GEM.

What is the issue with the 4WD system ?

How do I fix my 99 blazer the dome lights won't turn on and the 4 who drive won't light up or work


In the instrument panel fuse box fuse # 8 CTSY LP 10A ,that's for the dome lights, fuse panel is left side of IP. What are you talking about 4 who drive won't light up or work ? 4 wheel drive ? Do you have two speed automatic or two speed selectable ?
Switch Indicator Lamps Do Not Light - One or More ? Check fuse #15 IP fuse box 10A 4WD . This is for two speed auto !

Circuit Description

The indicator lamps circuits consist of 5 individual lamps contained inside the mode/range switch assembly, they are AUTO, 4WD, 2HI, 4HI, 4LO and NEUTRAL. The AUTO, 4WD, 2HI, 4HI, and 4LO lamps are contained inside their respective range button. When the ignition is ON, the transfer case shift control module illuminates the indicator lamp that corresponds to the current ATC gear position by providing a ground through a current limiting driver.
The transfer case shift control module flashes each indicator lamp after a shift has been requested and will continue to flash until the transfer case shift control module can complete the shift. After a shift to AUTO, 4WD, 2HI, 4HI, or 4LO is made, the transfer case shift control module will flash that indicator lamp until the transfer case shift control module receives a high voltage signal on CKT 1695 from the front axle switch.
A solid state circuit located inside the switch supplies ignition voltage to the lamps. The solid state circuit also receives voltage whenever the headlamp switch is in park or headlamp position. When the solid state circuit receives voltage from the headlamp switch it will reduce the voltage that it supplies to the indicator lamps, dimming the lamps when the headlamps are ON.

Service 4wd bad accelerator


Hi there:
The FDCM has a code, and for me to be able to correctly diagnose your vehicle..You will need to get that code retrieved by a scantool.\.

The service 4WD indicator gives an indication to the vehicle operator when the Final Drive Control Module (FDCM) has recorded a Diagnostic Trouble Code (DTC) for an electronic transfer case circuit or component malfunction. This indicator is controlled by the instrument cluster logic circuit based upon cluster programming and electronic messages received by the cluster from the FDCM over the Controller Area Network (CAN) data bus.

The service 4WD indicator function of the reconfigurable dot matrix Organic Light Emitting Diode (OLED) display unit is completely controlled by the instrument cluster logic circuit, and that logic will only allow this indicator to operate when the instrument cluster receives a battery current input on the fused ignition switch output (run-start) circuit. Therefore, the OLED service 4WD indication will always be OFF when the ignition switch is in any position except ON or START. The instrument cluster will turn ON the service 4WD indicator for the following reasons:

Service 4WD Indicator Lamp-On Message - Each time the cluster receives an electronic service 4WD indicator lamp-ON message from the FDCM, the service 4WD indicator will be illuminated. The indicator remains illuminated for about five seconds, until the cluster receives a lamp-OFF message from the FDCM, until the cluster arbitrator logic determines that another display request has priority, or until the ignition switch is turned to the OFF position, whichever occurs first.

The FDCM continually monitors the electronic transfer case control circuits and transfer case shift motor/mode sensor assembly to determine the condition of the system. The FDCM then sends the proper lamp-ON or lamp-OFF message to the instrument cluster, also known as the Cab Compartment Node (CCN).

For proper diagnosis of the FDCM, the CCN, the CAN data bus or the electronic communication related to service 4WD indicator operation a diagnostic scan tool is required. Refer to the appropriate diagnostic information.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

No lights on 4wd dash switch but fuse is ok. Can't switch to 4wd. Does it sound like the transfer case module or transfer case motor


Start with the simple and check the switch it self first. It's know for the the switch it self to go bad and will need to be replaced. The other common area to inspect is the wire harness at the TCCM, corrosion is an issue which can cause no current flow to your TCCM from the switch.

If all electrical systems check to be in 100% running order, good chance it's going to be your encoder motor (tranfer-case motor).

Thank you for using Fixya and keep us posted.

My 2000 Chevrolet Blazer is stuck in 4low. Today my "service 4wd" lit up on my dash. I asked a friend to check it out really quick. He tried putting the car into auto 4wd with my push button switch over...


Start with the simple and check the fuses and replace any one that has gone bad. Pay attention to the 4WD fuse and replace it is it has gone bad.
Thank you for using fixya and keep me posted, be glad to help you get your Blazer running 100% again soon.

Hi, I have a 2002 chevy tahoe with a major electrcal drain. I beleive it has a faulty 4wd switch too. could this be the problem?


If the battery is the factory OEM since you had the truck. It may just be at the end of it's life, most battery last only 4 to 5 years and then needs to be replaced. You can always disconnect the battery when you park it over night and see if the battery has keep it's charge. Just make sure you turned the radio off first before you disconnect the battery. Start with this and as for the 4wd switch, that would not pull any current when ignition is turned off. Good luck and keep me posted.
