Radio and Electronic climate control on my '97 850 Wagon just stopped working. There is no power going to either of them that I can detect. I pulled the radio and used the diagrams I could find online to check constant 12V and ign 12V on the radio harness. None was present. I haven't checked the ECC harness because I couldn't find a diagram.

Found a similar post where someone said they "jumped" a constant voltage terminal and got everything working again, but I don't know where they jumped from our too. Post is below. ANY HELP PLEASE. It's MN and I can't go without any heat at all.
