I have a Whirlpool WCP58580 oven, and I have a couple of problems.....1) when you open the oven door the light no longer comes on 2) it appears the convection fan is no longer working. Could this be a fuse problem? How do I know if a fuse is bad or which fuse to replace if that's the issue?

Look at www.repairclinic.com
They are a very good resource for appiance parts.

1.
If door latched:

1. Disconnect power from unit.
   
2. Check wires and connectors from control to door switch, then from door
   switch to control. If no damage to wires and all connectors okay, proceed to
   step C.
   
3. Replace door switch.
   
4. Re-apply power.
   
5. Press and hold any key down for 1 minute to clear F5 failure code from
   memory. F2 will appear. Press CANCEL and observe for 1 minute to ensure
   operation is correct.

2. If door not latched:

1. Disconnect power from unit.
   
2. Check wires and connectors from control to latch switch, then from latch
   switch to control. If no damage to wires and all connectors okay, proceed to
   step C.
   
3. Repeat steps A and B for door switch.

3. Measure door switch (door open = switch open small low voltage terminals).
Replace switch if defective.
4. Measure latch switch (unlatch = switch open,
CAUTION - oven light contacts are closed). Replace switch if defective.
5. If
corrections are made in any step, reconnect power to control. Press and hold any
key for 1 minute to clear R failure code from memory. F2 will appear. Press
CANCEL and observe for 1 minute to ensure operation is correct.
6. If failure
remains, disconnect power and replace control.

Note:
Applies to all F5-E... codes.

Ok, the first issue is the oven temp sensor. it is shorted. you will need to replace this device asap. Now, the second is is concerning the Self clean latch. it is not functioning and it is unable to be locked by the control(shorted). Use the procedure below to test this device.

I had the same problem. Hold down any button for 1 minute. That should reset the memory.

There is something wrong with the model number you've provided. Generally, there is often a door latch to move. Many older units have a door shield which needs to be positioned before starting to protect glass. Set the length of time you'd like the unit to run and set the control to clean. You may also have to set the temperature to clean. If you have a mechanical timer, set it so the stop portion is about 2.5 hours later than the time you're starting the cycle.
