No owners manual,so could it be a fuse or relay?wires are good.i am at a stand still.please help,and thank you for your attention.
No owners manual would help there,
but why have you not purchased one
for the items it does offer, you may need?
If you were to go to Helm.Com & spend the
money for a Factory Service Manual,as well
as any & all Emissions & Diagnostic Manuals
& wiring diagrams
Only then-- can you work on your own vehicles
Why would you throw parts at it,speed sensors
& such?
You got codes & think they have something to do with
parts, NOPE- they do not
Could it be a fuse or relay?
Really-your guessing now & haven't even
checked those items!
Wires are good you say!
You have a factory wiring book from Helm or AllData
& did some testing with a meter,actual voltage drop tests?
Need proper reference material & info BEFORE you even
walk to any vehicle made from 1981 on with an obd system
You can not find or solve any issue IF you DO NOT know how
the system works
Try Googling the question
Maybe someone on a forum asked &
someone provided what eventually fixed
the problem-for them of coarse & whatever
their problem was

I had similar problem with my 2002 Jeep Liberty when it was new. Speedometer went crazy when I turned on the heater. As i turned up the level of air, the speedometer was directly affected. Turned out it was a loose grounding wire in the dash, and the air pressure from the heater caused it to move and lose grounding. I would guess you have a loose wire somewhere. But on the plus side, you aren't putting as many miles on your odometer...

I have a 2002 Jeep Liberty Limited with the same problem. The main problem I have found to be the routing of the speed sensor wires located on the rear difrential. They are 2 blue wires on my jeep and probably the same on yours. The problem is that they rub on the E-brake cable and once the wire is exposed they short and the speedometer and any other options running off they speed sensor quit working and that includes the tranny shift points and can cause the torque converter to not unlock and cause stalls. I am having the same problem for the third time and chrysler and jeep are both aware of the problem and unwilling to repair the problem or post a recall.

The fuse it doing it's job, you have a short ( Wire that is connected to a ground, that draws too much power )
If you have an electrical schematic ( Repair manual ) find out which wires are connected to that fuse and check them for any chaffing, cuts, unnesassary twists, or corrosion.
If you have a ohm-meter, isolate the system ( by disconnecting the fuse, and other connections. Then check for any resistance on wires that should not be connected ( because you disconnected them ) by having one Lead on the wire's connector and the other meter-lead on your car's frame. A good wire will not have continuity if it is isolated.
