Ya the H2 has the cab forward effect. I havent tackled it yet as it really isnt a major issue but I would think it would be easier to get to it from under the vehicle. I change my oil by placing the vehicle on ramps. With the height, I could practically walk under it Ok exagerrating but I will check next time I change the oil and update.

 

more than likely it's a bad stepper motor in the guage cluster. It was a common problem on older H2's and eventually more of your gauges will go bad. Do a search on eBay. There are several places that will do a total rebuild....replace all motors and lamps for under $200. I had my 04 done a several years ago for about $150 and haven't had a problem since. The cluster is very easy to pull and send in for a rebuild and you get it back in a couple of days. And you can still drive your H2 with it removed.
