1st problem would be rear power windows not working from any of the switches.
Front power windows work just fine, but the rears don't. They died over a year ago and I haven't found a solution (I wasn't looking for a long time). The strange thing is that one of the windows died about a week after the other.
I took my car to an car electrician and I was told my window motors were bad, but after a while i tested them manually from a battery and they seem to work.
When I click on any of those switches I hear a loud clicking noise coming from the driver's side footwell, which probably means it's a relay clicking. I have not tried replacing the relay because front windows work fine and from what I read all power windows use the same relay (but then again there is not a lot of info about it and I might be wrong). Also, I suspect that the main power window switch could be bad and maybe it's not letting power through to the other switches, because I was told by some volvo fans that if the main switch goes the other switches stop working, too, but It's also a question mark for me.
2nd problem is high diesel fuel consumption on the highway.
City and combined consumption seems good, but once I get on the highway and I'm cruising at 130-140km/h the fuel consumption is roughly about 8-9 liters per 100km. It used to be about 7 to 7.5l before.
I took it to a garage and they did some diagnosing. I was told my MAF and fuel pressure sensor parameters are not within their boundaries and both of those got replaced. For a while I thought it got better, but after driving some more I noticed that I still don't get the same numbers as before.
It is getting colder outside, but I've had this car for about 2 years and it wasn't affecting it this much anytime before.
It is a euro 3 diesel and all it's eco systems are in place. No egr delete, calatytic converter is still there and seems to function fine (no rotten egg smell that would indicate it being clogged), the power is just as it was. Also I used an egr cleaner spray but nothing changed. Engine is running the same as before and computer is not showing anything else.
Thanks for any help I can get.
