'97 Gr Caravan - No Heat On Pssngr Side

[stb100]

I know...NOT the month to worry about this, but it will be soon enough...

THANKS in advance for any insight.

No heat blows from vents on psngr side. I've run a diagnostic on the system as per instructions in manual -- push a combination of dash buttons to run hot/cold air thru it's paces. During this test the actuator works and hot air does come out of these vents for a moment or 2. Once test cycles thru, though,it doesn't. Just cold.

I'm told the actuator needs to be replaced. Question is how easy (or hard) is it to do). And how costly? Anyone ever done this...

I'm happy stowing extra blankets on board. No other tribe members are, tho.
