Kenworth air conditioner controls

Yeah, there're cheap and must be handled gently and keep a spare around. I've looked for metal aftermarkets, so far no luck.

 

Havent had issues with mine, i do hate em though. If you pull out the whole HVAC controller with the 3 knobs on it, there is a metal line that goes to em, i spray it with WD-40 once in a while and they work great. If you dont they are tough as shiet to turn.

 

Here in the south, another problem is setting the ac at a comfortable level; if the heater valves are open, the ac won't cool enough when parked, and as soon as you close the valves, you need to defrost the w'shield. I also added an adjustable thermostat to help, wish I'd done that years ago!

 

Now that sounds like a CHEAP fix!
LOL

 

I agree, and do this, but with our humidity, you also need a little heat to help "de-fog" the windshield. Just last week, I was driving on a curvy, narrow, two lane road, that follows one of our many bayous, where your glass seem to pickup moisture from the waterway, and constantly fog up. Heater valves being shut make for an "interesting" drive.

 

I'm learning that FAST myself!
