Hi Guys,
I haven't dug around too much into this problem yet because I'm not sure where exactly to start. I have an 86 300E which is running well. The only problem is, the heater/AC motor doesn't always blow. Some times it does, sometimes it doesn't. So it's like this. Sometimes I get into the car, begin to drive and the fan won't kick on. I'll be driving for a while (the timing isn't consistant... sometimes within 5 minutes, sometimes within 20 minutes) the fan will just begin to work. So there's a bad connection somewhere.

Sometimes when I'm driving and the fan isn't going on, I punch the switches on the dash in an attempt to get it to work. This doesn't do the trick. I was thinking the dash panel was giving up the ghost, but I wanted to get your opinions first. Is there a culprit point that often gives out?
Thanks
