So, slight squeaking from the climate control blower fan. Any repair/lube options there if I dismantle things?

 

I think the D1 and D2 have the same one's. I pulled mine and cleaned and lubed it. I used some RP spray to lube and it went is just fine. That was about 6 months ago in the early spring and I had no problems with it constantly on high for the a/c..
