The battery died on the car and needed to be
replaced. I jumped the Buick and when it started
running again the air ac air flow would only come
out of the defrost vents. The dash and floor vents
aren't working now.

If he battery needs to be 'replaced' you should try that first. Also, you could be having a problem with the Alternator. At 15 years old, this should not come as a surprise. Also, a bad alternator is a serious safety risk, that can mess with any electrical system in the car: turn off brakes, turn off steering, de-prioritize AC in favor of defrost, etc. Hope that helps, good luck!

Air only blows out of front vents (not from bottom heater or defroster) on 2002 Buick LeSabre I am only getting air to come out of the front vents of the dash. My blower speed works fine. I can switch it from hot to cold no prob. Had one mechanic look at and he replaced the blower motor which did not fix problem but another story as I was pissed they ripped me off as it did not fix problem. Any quick fixes that I can possible do? Pep Boys said bring it in but will cost $45 diagnostic first. 7 Answers
