I have a 96 lss non-supercharged that the heat is sparatic and sometimes blows hot on the drivers but not passengers, it has a new radiator in it. and full of coolant, usually i have to shut the car down and remove the climate control box and turn key on-off a few times then itll work but not always.


Moved to your own thread. <---Toddster

Hey Taylor,

I moved your above post into your own thread.

So when you say you have to remove the climate control box; what are you actually doing? Taking it out and unplugging it?

yes remove from dash and unplug is what i meant.

Have you looked at the passenger side air mix actuator and checked the vacuum lines under the dash?

Are you able to take a photo of your dashboard for me?

I'm curious if your LSS has a cabin temp sensor.....if it does I would also check that as well. If its dirty it would send weird signals to the AC programmer.

On the Bonneville'* the sensor is behind the upper dash molding. It has slots in the molding allowing airflow to go through the sensor.

If your able to post up a photo I could determine where it is and then help you to get to it to clean it.

No since my accident and we thought the tranny dropped 3rd and od its been with my dad and at our mechanics. ill snap some when i get it back shortly in a few days. (about the trans it wouldnt shift past 2 good sbut it was the coil pack as for it was only running on 3 holes and not running right and everything was messing up)
