any suggestion ..... It has been doing this more often than usual ...
4wd light comes on intermittently but does not engage the 4wd even though the switch is on 2wd
4WD light comes on when car is started even though it is in 2WD. After car has been turned off and started again, the 4WD light may or may not come on, there is no pattern to it coming on or going off.
My yellow 4WD light just came on for the first time last night, but I've suspected major suspension problems for a while. The car drives with a constant tick/rumble from about mid-car, underneath. It sounds like someone put a playing card in the spokes of a bicycle wheel. It has also felt like I'm hydroplaning slightly when the car warms up and i'm driving normally. Rear shocks need to be replaced, for sure (since it doesn't do any kind of bounce back up when i put weight on them), and I'm worried maybe the whole tail end is screwed up from too much "unshock absorbed" driving. After heavy driving (double what i normally do) last night, the green 2WD/4WD light-up wheel lights all disappeared and the yellow 4WD light came on. It now sounds like I'm dragging something when I try to drive it. I'm taking it in on Monday.
4wd light on dash port comes on and stays on when I start the engine (this happens when engine is at idle -RPM=750). The 4WD light goes off as soon as I push the gas and RPM passes 1000. Please advise. Thanks
