The heaters on my front seats suddenly stopped working and after reading all the posts here I suspect it is likely the plug to the CCSM. There are numerous posts here describing melted plugs, bad grounds, etc. I attempted to remove the plug to the CCSM to have a look...but I'm embarrassed to say that I can't seem to get it unplugged!! I've removed the CCSM from the seat to get better access to the plug but still can't seem to remove it to check for the burnt connection. What's the trick to removing the plug? I've already managed to break the tab on the plug while trying to remove it and I don't want to do any more damage. Maybe it's melted and fused together? Help!!
