Greetings ladies and gents,

I am new to the (Volvo)forum and am humbly asking for some advice here.

The story:

I have a 2002 V70 T5 that had a perfectly working keyless entry system until about a month ago. My rearview mirror had the liquid stuff start to bubble so I went to the salvage yard and pulled another mirror from a 2004 XC70. This is when the remote no longer responded. Upon some forum reading, I found out the receiver is built into the rearview mirror? I took it to the dealership and they reprogrammed the unit and said all is fine now. BUT the remote is still not working. I did replace the battery in the remote as well as cleaned the contact points. The dealership said they checked it and it is emitting a signal nice and strong. Also of note is all the doors lock and unlock with the key in the door. So to my knowledge the motors in each door work. Is there an antenna or separate receiver module that I can check to see if it is working or not? Even better would be a link to a wiring diagram to the keyless entry system.

Any ideas?

Thanks in advance.
