The A/C button on my 03 Malibu LS blinks on and off in the summer when it's really hot. The only way to get it going is to open my left passneger window to create a draft and **** out the cold air from the a/c. If i use the ac with the recycle air button, the recycle shuts off right away and i have to keep it pressed in for it work. Now my heater is not working. There is no hot air blowing out at any of the dial settings. Can these two problems be related?
I own a 2003 Malibu and had the same problem. I found a fix online where you take the panel out, clean the contacts with alcohol and then take a #2 pencil and scribble some lead on the contacts then replace everything. I know it sounds crazy but it fixed mine. It started to do it again this year right before it started getting cooler out, so I haven't done it again, but will before it gets hot again. Can't say anything about the heat...mine hasn't done that!
It may be related especially if the problem is mechanical in nature. Normally there are panels in the AC unit that channels the air through the car. Have it inspected. Also have the AC cleaned out. This may also solve your issue.
