Shot in the dark, is there extra fuses on trucks anywhere?

If it were me I'd pull something like your radio fuse and use it until I could get another one. You know one that you truly don't need at the moment.

 

Each CMV (except those towed in a driveaway–towaway operation) must have the following emergency equipment:

• Fire extinguishers
• Spare fuses
• Warning devices for stopped vehicles

See 49 CFR 393.95 for full emergency equipment specifications, regulations, and exceptions.

Just a fyi/reminder to pick up a fuse assortment at the next opportunity.

I second using the radio fuse.

I'm not familiar with the International LT, but there MIGHT be a fusebox under the hood that MIGHT have some spares.

Good luck!

 

Sounds like you're low on freon, driver... I had that problem in one truck, but I was able to add freon through a valve in the system, just had to buy the right kind of freon first. Some folks said the system freon should be evacuated and recharged by a mechanic, but in those days a driver could simply add freon and the system would blow cold again, provided there was a valve to do this. I bought a can of freon which came with a hose and fitting for the existing valve in the system, and it worked perfectly... truck A/C was back to polar conditions. Dunno how much modern trucks have changed in this regard, but there was a time when drivers could just add freon and solve the problem. Having no cold A/C sucks, especially in hot humid weather...

P.S. Most truck fuse boxes have slots for spare fuses & relays... if they're empty, someone has already used them for other purposes. Time to buy some more!

Yes trucks have Freon. There's going to be a shrader valve on your firewall. Most likely on passenger side. If you buy the Freon with the fitting on it, it will only fit onto 1 valve making it impossible to f up. Fill it with Freon and see if it fixes the problem

 

Been in the 90’s here in Tejas this past weekend.
