1999 Chevy Venture Van - AC not cooling, recharged and it worked for a couple of days but quit again, we figure it was a leak. The fan switch also does not work on speed 1 but will work on other speeds. Now, the battery is dying. It will jump start but will be dead the next day. Could these two problems be related and what could be killing my battery?

,, check your output voltage at the back of the alternator or a easy way is strat the car and disconnect one of the battary termianls and see if the car is still running,, if not your alternator might be bad ,, local auto zones will check it for free if u take it out ,, but don't untill u have check other things,, fan switch has a resistor in the heater core box ,, one elment might be bad in it ,, make sure the alternator is charging the battary try what i said unplug it while the car is runnging the battary terminal one of them .. don;'t do this for to long , you can blow the diodes in the alternator ,, so jsut check and if it runs then shut it off ,, its not your alt if it keeps running after u disconnect the terminal

See link below for some common areas of freon leaks on this van. There is a link to pics in about the middle of the page.....
