Hi! Has a Suzuki Vitara XL7 2007. 🚙Something wrong with 4wd. Sets the gear in 4wd, the light on the dashboard lights up, but the car does not run in 4wd. No noises or anything else. Only works on the rear wheels. Do you have a poll? 🙏
Ha en fin dag!
Have a nice day!

Sounds like something inside your front differential.
Does this help? -
The website is showing a connection error. Can't get it.
Umm, it still works fine for me..
Thangs! Nothing helps, just the light in dash. It is a kind of motor, MOTOR ASSY, FREE AXLE. maybe this is the issue.
pt.
Since you said there’s no noise at all, when you switch to 4WD, I’d start by checking your actuator pump near the front differential.
Quoted from the linked website - I suggest 1st determining if the actuator pump is actually working. You CAN hear it run momentarily when you shift to 4WD, with the key on (engine off) if you listen carefully, or have a 2nd person listen. It is located on a bracket bolted to the back side of the passenger side of the front bumper. If you hear nothing, then pull the power lead to the pump and check for 12V to it when you shift the lever. If no power to the pump, start running through fuses, wiring and the transfer case switch connections to see where the "open" circuit is before you put down hard earned $'s on a new pump. 😉
You can access the pump by just crawling under the front passenger side. Pull the air lines, the electrical connector, and remove two mounting bolts. That's it...5 min at most, and NO need to remove the front grill. You don't even need to jack up the front end! Just be sure to get the air lines on the right nipples when reinstalling. See actual pump pic in following on posts.

4WD CONTROL SYSTEM (Service Manual quoted.)
When the 4WD switch is turned ON by shifting the transfer shift lever, ECM (PCM) (G16 and J20 engine models) or 4WD controller (H25 engine model) actuates (energizes) the air pump assembly. Then positive pressure is sent from the air pump assembly to the actuator installed to the differential case and causes the axle lock clutch and the free axle hub in the differential case to be engaged, resulting in the 4WD mode. Only when running in the 4WD mode, front axles are joined to differential case, and they become free when 2WD mode is used (or when transfer shift lever is shifted to N position), thereby reducing the power loss."
The free axle hub, axle lock clutch and actuator are installed in the differential left case. The positive pressure produced in the air pump assembly is applied to the actuator which then pushes the axle lock clutch to be engaged with the free axle hub. In this state, the drive force is transmitted to the front axle, resulting in the 4WD mode.
When the actuator is free from the positive pressure [when it is under the atmospheric pressure], the axle lock clutch is pushed back by the return spring force and cannot be engaged with the free axle hub, resulting in the 2WD mode."
