Thanks for using JA
The most likely cause is a software malfunction in the climate control module.
the module needs to be scanned for fault codes, and then have the software upgrades checked. the dealer is the only place that can check for the software upgrade.
Thanks for the detailed listen. Appreciate the very kind words and wish you the best.
you'll have to visit the dealer if you want this fixed. That is what the vehicle you drive dictates. that is my discussion. It takes a lot of hard work and training to be able to work on Volvo's 99% of repair shops out there refuse to work on them. and that is no lame answer!!!
