Delt with the insane pool for the top components. Had the pump rebuilt by top hydraulics and replaced the top module and exhaust note .odule and cleaned all the nasty corroded plugs. Took it to Cavendar caddy for a module reprogram( suggested here) and after.4.days the tech has had no luck so they, like GM, are punting it back at me. They did get the ac working again so now that winter is here I might use it a few days until spring. The top was working fine until the corrosion ate thru so.e things in the module. The switch has no effect but the pump is working cause now the Trunk will open. I guess I should be happy with some function.any ideas on where to step next?
