In Cab condensation issues

[mtnplower]

Does anyone else have issues with condensation inside their cab windows during winter? 10-30 degrees

It gets really bad making visibility poor

What are your suggestions to fix this?

no, no cab

but...

1) turn up the heat

2) remove as much water( snow and ice) as possible

3) put fan on high

4) open window at top a crack, if possible

Condensation is happening because of a lack of outdoor air coming into the cab and flushing out the moisture from your breath and sweat.
Your cab has two air filters. Make certain the outside filter is not plugged with snow or dirt.
The HVAC control has a lever to select recirculated or fresh air. Control needs to be in the fresh air position in cold weather. Recirc is for max AC.

Is your A/C working properly?
Recirculating air is one reason, but The A/C working makes the condenser, condense the moisture on the coil and remove it from the air hence dries the air out.

Check airflow amount. If filter is clogged, the condition could force the intake from fresh to recirc .
The air intake needs to be in fresh.
Not sure if cab tractors turn on the A/C or not when heating or defrosting. Cars and trucks do this to dry out the intake air before heating it up. If all seems to be OK as far as airflow amount, direction and temperature, you can apply Rain-X to the inside of the windows.

Also point the vents towards the windows. Also I keep my back window open about a inch.

Simply try turning on the Air Conditioning(AC).
It's probably all you need to do!
Above suggestions also apply as well.
Good Luck!

A/C should NOT be able to come on below a certain temperature(40*F ?? ) ! The mfr of the A/C systems determines that.

What may help, is to put on high heat- recirc mode to get the cabin warm/hot, then crack open a window, put on 'fresh air', to get rid of the moist air.
'recirced' cabin air gets hotter, faster than always new, frigid outside air , so this should 'clear out the moisture faster.The less snow you bring in on your boots and coat, the less condensation you'll have.
I had to scrape off the ice on the INSIDE of my CJ-5 windshield until someone said 'knock off your snowy boots'.......

Exactly what I do. Works great. You can see here in this link, they even recommend it for your vehicle.

I carry a small hand towel on a hook in my cab and when I first start to work and the condensation starts to show up I give it a quick wipe down and usually only have to do that once and then the system is up and running and takes care of the condensation after that.

This is the same as is done in cars these days but is automatic when turned to defrost mode. Heat and A/C on at the same time. They used to have ambient stats back in the day that kept the A/C off below a certain temperature and defrost was heat only. Use to destroy compressor seals as they would dry up over the winter from lack of use.
