wiper motor not getting 12v
 

2004 Santa Fe
metered on voltage to wiper motor only getting 4.9 volts
wife has been having issues with wipers for about 3 weeks
and over the last week car did not also start.
battery is new and getting power went running.
yesterday she went to store and after going back to car it wouldn't start no wiper and issue with heater fan. She waited and it started. I did some checking today. I have removed wiper unit and I went to auto parts store, dealer and to another store no problems with starting or the heater. Anyone got any idea's or where I can get the wiring diagrams for power feed to the wiper motor

Sometimes you can get lucky with Autozone wiring diagrams. You just need to enter the correct info for year,make, model etc. I don't know if Hyundai diagrams are available there , but the diagrams I have used from there were pretty good.
