windshield washer motor replacement

My windshield washer motor on my 2000 Trooper is dead. How do I get to the motor to replace it? It appears that access must be from below.There is a piece of fascia , flexible rubber or plastic over the wheel, and I think I see the washer fluid container body there. Do I remove that fascia? Does one have to replace with Isuzu parts, or is there a generic part readily available?SZ
