L series

Has anyone solved the auto HVAC problem blows hot air for 10 mim
then changes to cold air automatic, if you change the temp by 1 degree
it will go from hot to cold and so on back and forth

 

Even tho my L was just bought back as a lemon (due to other issues), the
heat/air never did get corrected even after having the latest TSB done on
it.
I will miss my L, but I won't miss the heat/air troubles in the car.

 

What years and models did this affect? Is there a TSB on it.

Haven't seen this yet on my '01 LW300 - Oppie

=========

 

mines an 03 and somewhere i saw a TSB posted and someone said it didnt
work, I did have the reprograming done and it didnt help i try to run
it on the manual mode as much as possible but it will still send a blast
of cold or hot air i would think it is a software problem. but my dealer
dosnt know of a fix will be taking it back in soon for service will
ask again

 

Mine was an 03 with the auto climate control.
Yes to tsb according to my local service manager. Yet it did not work
recently when tried on my L..
Lots of posts on Saturnfans.com from others with this and other issues. It
is also a great site that has Saturn techs there to help you out also. They
were awesome when I recently needed them.
