Can anyone tell me where I can find/buy a schematic for the 2002 instrument cluster? Mine is the 1500HD, with trans temp. The trans temp gauge stopped working. I traced the problem to U1 on the printed circuit board. But the IC is toasted to the point that I cannot read the part number printed on it. This also took out R39, so I need it's value as well. (Just shows an open when I try to read it with an ohm meter.) Any help would be appreciated.
