im having oproblems with my power door locks. both are not working. first thing i did was change the swiches (they were both bad) but still not working. so then i cut into the power and ground running to the lock solenoid, thinking the solenoid was bad. Luckily both colenoids are still working great when you connect them to a power supply and ground. so then I started checking for contenuity accross the wires. I saw contenuity from the power wire for the swich from both ends (drivers and pass door), but showing no ground either swich. (am i suppost to?)i checked the wires at the first connection they make after they go under the dash from the pass door and they look good. I aslo tried cutting the ground from the pass side swich and grounding it to the door. this made a cool spark, but still no locking action. from here on i really dont know what to look for. i'm guessing i have a bad ground under the dash??? any help would be great. a wiring schematic would be heavenly. thanks.
