hello,

my girlfriend's 740 has a problem. the climate-control system is stuck on defrost. adjusting the control lever to the various other settings has no effect. i own two 1800's and consider myself to be a pretty good DIYer (hope i dont break my arm patting myself on the back), so i decided to dig into the dash in an attempt to fix it. to my horror, i discovered that the lever actuates a dial (or something) that uses vaccume(?) hoses to opperate the climate control vents. obviously, it's winter, and it's cold; and the defrost setting does a poor job of heating the car (cold air comes out of the dash vents), so it needs to be dealt with. my girlfriend and i are both poor students, and we're hoping that we wont have to take the car to a volvo repairman. is there anything i can do to repair this system?

any advice or help will be much appreciated,

ryan
