Pontiac Repair: 05 Grand Prix, grand prix 1, cap lamp

Question
1.  Low washer fluid light on all of the time, even when tank completely full.

2.  Check gas cap light on.  Replaced cap w/after-market.  

Any suggestions?  Thanks in advance for your help.

Answer
Hi
1)Fluid level sensor in washer resivoir.
2) EVAP system leak CAN also cause the Check gas cap lamp to come on.
I would take it and have the computer system scanned for trouble codes.
You VERY well may have a small leak OTHER THAN the fuel cap that the system thinks is the cap.
I Hope this helps
