Couldn't push in tractor valve.

This morning it was -12 out. Like most of this winter so far.

but I couldn't for the life of me push the button in. The trailer one went in just fine.

I finally got it in after warming the truck up and started heating up the cab.

do you think this was moisture buildup in the valve itself?

Never had this problem before and it sits outside every night.

 

yes full air and dryer works as it should.

I was pushing as hard as I could several times till it went. It wouldn't budge at all.

air dryer is new from the fall. I never have water in my tanks. It's the first air problem I've had this winter.

ill see if the problem exists Monday morning. If so I'll put in new buttons I suppose.

truck also was at 80psi when I started it, it doesn't lose much over night.

 

Truck sits outside for 14+ hours every night and weekends. Just with a block heater so the cab is just as cold as the outside temp. It's been negative temp most of this winter so far.

it just seems odd that it wouldn't push in no matter how hard I was pushing.

i got it in after I slightly warmed the cab. I was also stabbing my brakes and pushing the button at the same time and it finally went in.

i set my tractor brakes probably 100 times a day and that's probably a lowball some days.

Its going to be -17 Monday morning so I might just warm it up for a hour before I take off.

 

I've tried that but my truck doesn't hold the heat in that well because it's a sleeper, even with a 1500wt space heater. I back in my driveway so I don't have another cord that's long enough.
