VSM Help
 

I have an 02 F35O Lariat, CC, LB, 7.3, 4X4, ZF (6 SPEED). Dome lights work intermittently, key fob not at all, radio stays on door open key removed.
I have searched four different dealers for a VSM that matches my truck's build info, the part number I am searching for is 4C7Z-15604-AC and all I have found is that it's a discontinued part.
Anyone know where I might find this p/n VSM?

Crap. I have similar issue. Radio stays on, dome light on, key out and passenger door lock won't work. I will look for this part as well.

I have a similar problem. My dome lights and radio stay on, and my fob doesn't work. The dome lights and radio will time out and turn off.

The VSM problem is a well known malady especially with the 02, maybe because it was the first year build with a VSM instead of the GEM. I do not know. A lot of people on this site have posted on this problem but you have to search for most of the post due to them being fairly old. I would advise due diligence when troubleshootingVSM related problems. I am pretty sure my VSM is the root to my trucks ailments but it will not cause me to not be able to drive the truck, if it was to kill the truck then that would be another problem. I will keep looking for a replacement but it's hard to find the exact part number I am looking for.
Good Luck,
Bill

Can anyone tell me if different VSM part numbers are interchangeable or can I use any VSM in my 02 Lariat?
