So heres the details if anyone can help , 1998 c5 with 6 speed and all stock . the drivers side heater blows cold no matter how hot i turn the dial up but the passenger side blows normal or hot as it should . if i disconect the battery for a while and drain everything in the puter it blows hot on the drivers side for a while then back to cold . i pulled the fuse by mistake for the hvac and it worked for a short time as well so i figure the same thing as doing the battery thing . the fluids are all up to snuff as well . any ideas and maybe what repair manual should a person buy to help maybe .
