Gauge and wipers issues...

With all the drama I caused with the 318 or slant 6 post I made a few weeks ago...I have decided to keep the 225! Now I have a couple of problems. I think I know the answer but I need HONEST opinions!
1st. I have a 3speed wiper motor, the wipers are very slow to come on, park or change speed, Ground problem, switch or motor?
2nd. The temp and fuel gauge are erratic as heck! Temp gauge sweeps all the time! Fuel gauge is "working" then buried below "E"! I fought this problem only to end up replacing the instrument board due to broken studs. I think the IVR is failing. The temp sender is new and the fuel sender seems to ohm out ok. Be honest and any advice will be a great help! :violent1:
