Remove the screws, pull out with a trim puller.
Try a Freightliner service department.
In order to find instructions on how to read the fault codes of a 2000 Freightliner FLD 112 with a C12 engine you should go to heavydutypowertrain.com where they have an extensive selection of instructional material including how-to videos.
Try replacing the speedometer switch on the transmission.. that's probably your culprit.
It comes with whatever sized tanks the orignal purchaser ordered it with.
You won't find one without the make and model of the engine. Or, you contact a Freightliner dealership with the last 8 digits of your VIN, and they can tell you the part number.
To replace the heater core in a Freightliner FLD 120, start by disconnecting the battery and draining the coolant from the system. Remove the dashboard and any panels obstructing access to the heater core, then disconnect the hoses and mounting brackets. Carefully extract the old heater core and install the new one, ensuring all connections are secure. Reassemble everything in reverse order, refill the coolant, and check for leaks.

I assume you mean either the Severe Duty model or the Classic XL, In the glove compartment, on the bottom or on the door, there should be a sticker... it'll have the VIN, rear end gear ratio, transmission model, axle specs, etc.
The Freon capacity for a 1998 Freightliner FLD typically ranges from 25 to 30 ounces, depending on the specific air conditioning system installed. It's important to refer to the vehicle's service manual or the under-hood label for the exact specifications, as variations may occur based on the configuration and options of the truck. Always ensure the system is serviced by a qualified professional to maintain efficiency and prevent damage.
Depends on which model Freightliner you have. If you have an FLD (120 or 132), you'll have to unscrew the panels they're mounted into in order to access them. It may involve removing multiple interior panels which overlap each other. If it's a Century Class, it should be much easier.. a lot of the times, the only thing holding those panels in place is the seal around the doors.
It's a simple remove and replace, BUT... you'll want to get a shop to recover your refrigerant first.. discharging it into the atmosphere is both dangerous and illegal. You'll also need to replace the receiver-drier any time you open up that system and expose it to atmospheric air.
Behind the glove compartment, there's the fuse and relay panel. I don't remember specifically which one it is, but there should be a diagram on the back of the glove compartment door. It'll be the same for most FL models up to 2009, including the FLD132 (Classic XL), FLD SD ('Severe Duty' model, bearing some resemblance to the Kenworth T800), etc.
