Okay so I have a 2001 4runner sr5 sport and I noticed my 4wd indicator light is flashing all the time. My 4lo still works fine but I can't tell if my 4hi works at all. The button on the side of the 4wd shifter is out (where my 4hi should be off) but I don't know if it is. It seems like the ride is getting worse. I tried tapping on both actuators and still nothing. Anyone know something else?
