When I flip my awd on the light comes on by the switch but the front will not lock in. My speedo is not working either. I read somewhere that that is the problem. Any other ideas?

Sounds like the speedometer sensor. It's actually called a Hall Effect sensor. It will be on your right front wheel on the brake carrier. It will have a wire coming off of it leading up into the headlight pod. If your mileage and tripometer are working but the speedometer isn't, the Hall Effect sensor is probably your problem. If nothing works on the speedo, then it may be the speedometer itself. My bet is on the sensor though. Had the same thing happen on a friend of mine's 2002 500 sportsman several years ago. Put a new sensor on and that fixed him right up. Hope this helps and good luck.

Yeah everything else works but the speedometer it's self. I'll buy one and try it. I just found out from the guy I got it from that he put 90 weight gear lube in the front diff switch I know is not right

you will have to flush it out a few times if he did...if the speedo lights up and shows hours...the hall effect sensor is gone or dirty ..but the AWD should work ....but you will need to clean the heavy weight oil from the Hillard diff...may take 2-3 times before its cleaned out...

I got a quart of demand drive fluid. So I'll flush it out. I just ordered a speed sensor so I'm hoping one of them will fix the problem

Haven't replaced the speedo sensor yet. Just ordered it yesterday and I haven't had time to flush it out yet either. I'll keep you updated

I have the same type of issue with my 03 Sportsman 600, replaced the hall effect sensor and the gear selector switch... the speedo now works but the AWD will only engage when the override button is pushed. Thinking it may be a ground problem

Mine took a few times to do it. I turned the key off held the button for 15 seconds not 10 and then held it as i started. Then when it started it came up with the battery and wrench symbol and then i hit the overdrive button untill i found the awd selection. Took me atleast 3 to 4 times

My 04 600 cluster all works but the speedo needle don't move. I had the quad on jacks stands and put in gear and at slow speed the rear tires turn and then when i rev more all 4 turn fine. I put it in 4wd and all 4 turn just fine and when i ride it seems okay but no speedo needle moving. Can I clean the wheel sensor maybe? I can't find a new on online anywhere under $65
