Alright, ordering some accumulators and will be picking up a windshield seal and MB hydro fluid for the SLS from a nearby dealer. I thought my only issue with the HVAC was no a/c. The ignition was keeping the blowers from working while engine on. A jiggling of the key got the blowers to work this morning, but they seem to blow only cool air, not hot, not cold. So, I thought I'd have all winter to get the A/C working. But, with no effective defog, that could get dangerous. If that temp sensor mounted between the center vents goes bad, could it cause an issue like this?

Also, the engine seems to run very cold sometimes, like on a cool evening going 60mph, it will get down to 60*c. Once or twice on a hot afternoon, the aux fan kicked on and brought it back down to 80 from around 100*c, which seems normal.
