Dim PRNDL is the least of your worries on that cluster, 2003 were plagued with problems. Best to send it out for a rebuild and have all the issues addressed at once. I would be leery of anyone that does it for $100-150, because they may or may not know of all the issues these have and may not do quality work. See the pic below for an example of horrible rework. That is why I recommend professionals like Circuit Board Medics, you get what you pay for.
You can't "get it soldered down well enough" because you aren't using the right process for surface mount components. First you have to remove the solder you added with solder wick. Then use a good liquid flux and the proper solder with a good temp controlled iron and not overdo it. Then clean with alcohol and a stiff brush. It should look like the part circled in yellow in the picture after you're done. (my rework) :mrgreen:
Be aware that too much heat from cheap irons will damage these boards very quickly.
