For a while the new ones were on backorder. I bought one from Napa that looked like the same supplier as the Saab part.
There’s a lot of threads about ISM’s on here. People spill drinks into them, they wear quickly, and I really dont enjoy changing them out. Lots of plastic to disassemble.
Ps if ur worried about the electrical, make sure u have a good strong battery (get it tested at autoparts store). Tight connections to battery, and im told theres a ground point under the battery tray that can get corroded. Make sure its clean , tight, shiny metal.
