97 isuzu rodeo m/t 4x4 won't engage

I was wondering if anyone could tell me what my problem could be. Wheels will spin when stuck in mud/ice. Also, my air conditioning/heating won't blow out. You can feel cold air/heat coming out but won't blow harder when fan speed is adjusted (heard through someone that this could have something to do with the four wheel drive so I thought I might mention it). If anyone could give me any information, it would be greatly appreciated.

First question I have is did you check all of the fuses and relays? There are some in the driver's side of the dash as well as under the hood. Check both and see if one has blown then after that you'll want to check your wires to see if you are getting power to the transfer case. After that it's a matter of tracing your electrical from the 4x4 engagement button to the main fuses to the transfer case. Good luck

The fuses are not blown and I don't have an engagement button. It is a shift stick with 4L, N and 4H. How do I check if that is working?

confused about what you are saying/seeking....
your wheels spin when stuck in mud/ice -- so maybe you think your 4x4 isn't working? how to check it? when stopped, engine running, trans in Neutral, clutch in,put the 4x4 shifter into Hi or Lo and drive it. if it is working your front wheels will be driving/powering as well as the regular rear wheels. if you do this on dry pavement (not usually recommended) and slowly drive and make a turn you will feel the front wheels 'fighting' the turn, since they are turning at the same speed. to get out of 4 wheel drive, stop, put trans in N, put 4x4 shifter in N, put regular trans shifter in R reverse and back up a few feet to make sure front hubs have disengaged.

sounds like you need basic info on this, so to get the way things work you might want to try www.wikipedia (http://www.wikipedia) and/or www.about.com (http://www.about.com) .
it also sounds like you need the owners manual. you can try ebay or go to the source for owners manuals and the factory service manuals at

as to the blower, someone was pulling your leg, or your pulling ours. of course it has nothing to do with 4wheel drive. if this is for real the cause is either the blower switch, or more likely the blower resistor block that is used to adjust the voltage to the blower motor depending on the speed selected at the switch.

I have engaged my 4x4 while in nuetral and when attempting to drive, the vehicle did not move. Can anyone help with a way to fix this problem?

either the linkage is misadjusted or the transfer case is bad.(the transfer chain broke) or you didnt engage 4wd correctly. the sticker on the viser should advise how to shift it in four wheel drive has anyone had the transmission or transfer case out for service
