2003 Ford Windstar- How to fix this vehicle?

Question

I would like to fix this vehicle. I need location of repairs, how to gain access to these locations, level of difficulty, tools and parts needed. Also the interior lights love to blink in a pattern since I purchased it new. The dealership could not locate the problem. The passenger front window and door locks do not work. The A/C blower clicks when placed in the cold position. The heat stopped working. We think that the blower door is not closing to allow the A/C or heat to function properly. These are my codes: P0305, P0316, C1235, C1185, C1198, C1194, C1254, C1246, C1250, C1242, C1214, C1210, C1103, C1410, C1404, B1318. Thanks for assisting me.

Answer 1

P0305 Misfire number 5 cylinder

P0316 Misfire detection (upon start up)

C1235 Right rear wheel speed sensor input signal missing

C1185 ABS relay output circuit failure

C1198 ABS inlet valve

C1194 ABS outlet valve

C1254 ABS inlet valve

C1246 ABS outlet valve

B1318 Battery voltage low

ALL these "C" codes are for the ABS system some of these are memory code that where pulled, you would need to clear the ABS code, This is mostly due to a ABS module failure. If the interior light do not work and the door lock this can be related to the front electric module (FEM).
