99 STS and has a couple heat realted issues (no heat on drivers floor) and appears (just noticed this) that the drivers side temp control does not work (always full heat on that side reguardless of setting, pass side blows less and cooler with temp changes).
heat has been good enough that I am hopeing to leave till summer and look at blend doors and such since heat is there, its just not on drivers floor.
But 2X (strange its only happend 2x all other 60-70 starts in last few months have been normal for heat, even in 10 below)in last month a strange thing has happned. Car is fully warmed up (12 o clock on temp guage) yet no heat. The heat does come, I think i hear a door move then all the sudden there is heat.
Im in ND so its cold, the 2X this has happned has been the coldest days we have had, 18 below and today it was 27 below. Normally with the autostart i have heat in 7-10 minutes and am is blowing full heat by 15.. both time it was wierd it was like 20 minutes of cold, then (and i might be mistaken) i thouhgt i heard a blend door like sound and heat was full (didnt slowely build, it was totally hot)... my worst fear was slushy or frozen antifreeze (it was checked this fall and was good to 30-40 below) and I'm thinking since its not slowely heating up, its not a freeze problem.
My guess is yet another door problem, colder, slower to work. Sound like I may be on right track? Got a long weekend so may pull glovebox, was really hopeing to outlast wainter but No heat for 20 minutes (even if its very rare) is getting to edge of "blow it off for now". Maybe i have something as simple as vacume line problems. been trying to get a good shop manual of e-bay but keep getting outbid in last 30 seconds (why does somebody alwasy want something for $.50 more then me, $10-50 more i understand, but i keep loseing by pennies
)
