Expert:  Lou P. master tech replied 6 months ago.
It sounds like it but first we can check the power and ground to the module. Do you know how to access the Module and do you have a volt meter to test with ?
Customer: replied 6 months ago.
i have Volt meter, I will check for voltage let you know soon thanks
Expert:  Lou P. master tech replied 6 months ago.

Just to be on the same page we are working on the right front door correct ? Also the front Sam doesn't have much to do with this door which I noticed you mentioned in a previous post.

Expert:  Lou P. master tech replied 6 months ago.

Fuse 22 is the fuse for the door control module. It's located in the fuse box on the left side of the dash. It's the second one down on the left column. Check the fuse also pull it out and reinsert it to see if it will reset the module. The power wire on the module that comes from that fuse will be a red wire , the ground will be a brown wire. They will be in a 5 pin connector that only 4 wires will be in. The red. Brown. A smaller brown wire with a red stripe and another small brown wire. Those two are the communication lines. Make sure there is no corrosion in those wires. Hope this information helps.
