95 freightliner fld120 fuse type

Those are breakers. I forget what they are called, but Napa,orielly’s and most truck parts stores will have them.
@Rideandrepair @jamespmack may know the name of them.

 

Auto Reset Breaker.

 

The fuses are in the middle. Pop that long plastic cover, you’ll see them. They’re all hooked to a bussbar, similar to a house fuse panel. The square ones are breakers as mentioned. Same stuff used in most Trucks. The problem I’ve had are few. The labels are usually all faded out. Can make it hard to find a bad one. Just have to hunt it down with a test light. The 4 way flasher is usually located in the lower left corner, and is hard to get out. My 99 went bad. It was an expensive “Heavy duty” flasher. whatever that means. I think it had 3 prongs. I used a pigtail and a standard 2 prong flasher on advice of a mechanic. Left it laying in there for easy access. It worked fine. That’s all I know. Never had a fuse or breaker go bad.

 

Get the breakers from Freightliner. Napa RAPES you for them.

 

Here is an old post that identifies them if the labels are bad/missing.

 

Our little FL60’s had the same setup and in 25 years and over a million miles the only thing in the box I had to replace was the flasher and the hvac relay. They'd last about 3 years. Used to pull the fuel system fuse that Cat required out of it when left parked in a sketchy place as an anti theft device.

 

Why would you? No, never have and never seen it done. I wouldn't, personally
