Where is the driver side blend door actuator on a 98 Seville STS?

I believe that the right side has a blend door actuator, and the left side or driver side just gets air from the regular flow from the programmer and vacuum motors.

(2005 cadi sts) I can drive this vehcile for months and, if I do not use it and, put it in the garage for a couple of weeks the battery drains. Ive had it in the shop and, the dealer could find nothing...

Sounds like the battery is a drain on it, check with an ammeter on the red or black wire to see how much. Shouldn't be over .2 A normally.

Also can try changing batteries, as when some batteries get old they do not hold a charge.

If you have the original battery, it's 5 years old.

Typically, batteries last 3 years on average.
