Hi all, Still working on bits and pieces of a new (to me) 86 5000CSTQ. I need to replace the interior temp sensor suction fan. I have removed lots of interior trim to still not have access to this bugger. Any suggestions so that I don't break any unobtainium plastic parts? I know graydon had a retrofit for a GM fan, anyone tried this? Thanks for your help, Randy Paquette
