 amendment to power lock fix
Resabed01 gave a great description of how to fix this problem. It is difficult but doable. You don't need any special tools. I didn't even use the suggestion to solder in the new resistor.
I followed the instructions and found the same disk resistor. With a digital multimeter I measured 3-5 ohms across the plates. I tried to find a 2.7 ohm resistor but couldn't easily get one. After thinking about Ohm's law I decided to try and modify the disk resistors. Increasing the current would lower the resistance. I simply crimped the disks with a vice-grip. The resistance then measured 2-3 ohms. I reinstalled the assembly and the lock still needed more power. I took it out and re-crimped it. It then measured 1.5 ohms. This worked great. The first door took about 4 hours because I was looking for the resistor. The second door only took 30 minutes, including panel removal and re-installation.
The gear case is tricky to remove. You'll have to remove the window track. Then remove the three screws that hold the door latch. The gear/actuator plastic case is attached to the door latch. The door latch is steel and the gear case is plastic. The gear case simply slides off the door latch, there are no rivets or screws. You have to wedge of screwdriver in-between the latch and gear case to disengage a clip (a mirror might help here). The gear case then slides off toward the outside of the car (you have to remove the screw driver in order to take it off completely). It helps to see the case before doing this. I found an auto parts store that had the gear case and looked at it before attempting to take it out.
Also, the gear case that you have to break open should be put back together by putting small screws where the plastic welds were. I found that the case was breaking open as the lock moved up and down. Just find the holes on the opposite side of the welds and drill through with a small drill. Then insert some 3/4" small screws. Don't over-tighten the screws.
After thinking about this solution I wonder if Rosabed01 isn't the original engineer that created the lock mechanism. Either that or he's above average. What normal person would have been able to figure this stuff out? Amazing. The next time you're in Minneapolis I'll be glad to take you out to lunch. |
