need more info.. is it a manual 4WD that you have to pull the lever on the transmission hump to engage the 4wd or is it push button 4WD?
i have a 96 olds achieva and my high beam light was flashing, i checked the headlights and one of my low beam headlights was out. once replaced the flashing stopped.
Depending on the vehicle, the 4wd could be coming on and off. The flashing could also be a code warning. Searching for the specific vehicle may give more specific answers.
this is the lever that enables high and low gear for 4wd.
If you're in 4WD low, then the vehicle needs to be put in neutral before you can switch it back to 4WD HIGH or AWD.
No special button, just pull the smaller gearshift down, and you will see the "4WD" light on the dash. down position is high 4WD and down and over to the righ and up is Low 4WD.
It's a U shaped pattern, upper left 2WD, lower left 4WD high range, middle right neutral, upper right 4WD low.
4 Lo(w) is the the mode used for severe low speed 4WD conditions such as steep hills and very slippery conditions . It is a very low range so any continued use at high speed will stress the 4WD components. The truck must be stopped and the transmission in neutral in order for it to engage or disengage.
High/Low Range To enable a 4WD to travel at lower speeds while traveling on rough terrain it needs lower gear ratios. Not all 4WD's have low range gearing and this restricts their ability to tackle rough terrain. However 4WD's that lack low range gearing are generally not built for severe off-road conditions or sometimes have a "crawler" 1st gear to compensate for the lack of low range gearing. The high range ratios in 4WD mode are the same as the gear ratios in 2WD. When low range 4WD is selected, the gear ratios are approximately half that of high range, although the exact ratio varies for each vehicle manufacturer. For example this means that if an engine speed of 3000 rpm in high range fourth gear is 65 mph, then in low range at the same engine speed and the same gear, the speed would be around 30 mph. Some points to note about low range gearing are: * You cannot select low range in 2WD mode in most cases. * You do not have to use low range as soon as you put the vehicle in 4WD, but only if the terrain requires it. * On most vehicles you have to be stationary when changing from high to low range, check your owners manual for your particular vehicle.
This vehicle has full-time 4wd. There is no option to make it rear-wheel drive.
the fuse is blown.
