One day out of the blue my dash brake light came on and the following things stopped working: cruise control, A/C, electric door locks, all chimes, intermittent wipers and the v-tech solenoid went out the next day. I've replaced the v-tech solenoid has been replaced but still having the same trouble code. Does the multiplex control or has anything to do with the v-tech solenoid?

I think we need to start with what code you are getting and that will tell us what direction to go. Here is a guide that helps with this if you need it:

To answer your question, it is related but it may not have anything to do with this issue but that is going to depend on the code.

So let us know what this is and then we can provide the testing needed to run through and find out what direction to go.

Thanks

Got it. That helps a lot.

So, we are going to have to run through this because you may have a wiring issue.

So basically, you are going to run through proving there are no shorts, and these guides will help with this.

Please see the attached for the testing that is going to tell us what is going on. Thanks
