Heater weirdness 86 5k

Hi gang

Could not find a similar problem in the archives so here goes. When I turn 
the climate control on in the morning it will work fine for about 10 minutes 
then the fan gets gradually weaker until it quits. Heres the weird part..
When I'm making a turn, (left or right does'nt matter) the fan will come back 
on until I straighten the wheels. I'm getting dizzy going around rotarys 
trying to keep warm.
Any ideas
