1983 300SD Glow Light Stays On

3 months ago I replaced all my glow plugs and used the reamer tool to clean out the carbon build up.

3 weeks ago the glow light stayed on after the engine started. I stopped twice on the way home to kill the engine and restart it.

3 hours ago my glow light mostly stayed on and I hit every green light on my commute. So I didn't stop and restart the engine. By the time I got home the battery was almost dead. Now I'm charging the battery and wondering about tomorrow.

82 300SD Heater blows warm at idle, not at speed

Re '82 300SD. Climate control switches blow air at normal rate (auto and full-on), but it only warms up at idle (e.g. stopped at traffice light). Otherwise it is cool but not cold. I replaced the thermostat; engine warms up quickly to operating temp. When fan turned off (not on auto or full on), I can feel nice warm air at side vents, so warm air seems to be in the hoses. But press the buttons and it's only cool air. Is this a monovalve issue? Something else? Thanks.

86 300SDL Turbo sunroof weatherstrip?

I R&R'd a new sunroof (Tilting)Weatherstrip.
Pretty much straight forward.......except
1: Found 2 rivets loose on back hold down bracket.
short of removing panels(trying to avoid)
any tricks to fixing? I tried a pair of needle nose vice grips, no go
2:The new strip prevents the roof from closing like the old one!
Should I "grease" it with something? If so what?
Thanks
