I still have yet to get around to this issue, but sitting here at work I thought I would dig around the web a bit about it.
I see folks have replaced the mode switches, but how about cleaning them? Never actually tore one down so I looked into it. Came up with this....

Curious as to whether it was similar, considering it is an ISUZU module, but from a '98 Rodeo. Shouldn't be much different if anything, I wouldn't imagine.
Thought I might give it a tear down and see. Could save me the $150 or so. We'll see.
Anyone know the part# for the mode switch? I don't have any of my software or docs here at work and don't exactly wanna call Merlin from work JUST to get the part#, heh.
