The indicator lights and their associated function for the heated seats, heat, AC, Heat, Front/Back Defrost, Trunk Unlock, STC, Rear Head Rest Pop Down are not functioning but the cigarette lighter is working. So basically everything in the panel immediately above the gear column is not working as well as the lights not being on. Any ideas or suggestions would be greatly appreciated. I have owned this 2000 Volvo S80 for 6 days. It's been a great 6 days but have I stumbled upon a lemon? Please advise

    same issue. I tried resetting the system with the fuse and by disconnecting the battery for a few minutes. Is there any way to reprogram without going to a dealer????

Your CCM (Climate Control Module) is dead, or asleep. Look in the fuse box at the left end of the dashboard and pull the fuse and see if it resets the CCM. The module may need to be reprogrammed or replaced.

My suggestion is that you take this to a Volvo mechanic, one who has experience with working on these 1999- Volvo models. They have a networked computer system that requires special tools to diagnose and download software into the modules.

Also, it is a good idea to have them perform a total software upgrade, it will address many issues, and may prevent other issues from occurring.

I have a 2000 volvo s80. My deftost, heat, heated seats or a/c isn't working. When I push the buttons nothing lights up or comes on. I am not sure what it is. It was working fine until last week

These are usually related to a FUSE. In the OWNER's MANUAL look for the FUSE section and see if the non-working devices are listed on the same fuse, and where the FUSE panel is located. Fuses can be purchased @ an Auto Parts, Hardware store or the dealer.

It could also be a relay for these devices. Look online in the Volvo Forums for more info.

OK, there are two problem spots here that you will need to inspect. i would advise to inspect the switch and the element functions. A bad element will show no continuity. replace the element in the seats if they are not registering continuity. I would also inspect the actual enabling switch for its operational value as well. test accordingly and replace if found to be defective.
