Outdoor life with Hunt4fish.
Trying to fix the actuator pump on the four wheel drive Tracker I have. The light on the dash is blinking on then off and it won't stay into 4wd., When you want 4wd it's not there so I decided to dig into it to see what the problem could be. Air actuator pump is located here Tracker suzuki etc - https://i.imgur.com/QK0cKj7.png
This actuator is the same on a lot of four Wheel Drive vehicles of that time period around 2000 or so and similar repair easy to DIY just take your time and be clean.
If light is blinking more than likely its loosing air either through leaking diaphragm, a little o-ring like mine or a simple gasket! As well check the rubber lines that go to the front drive-train system. If it's not working doesn't take much sometimes, good luck.
