Liking my $5300 T5 AWD so far, but unsurprisingly for a cheap, 10 year old European car, it isn't perfect.
recently, when my car has sat for a while (ie overnight) the battery sounds very weak while cranking over. But if I used the car and start it again, it sounds normal, and strong. I am assuming the battery is old and needs to be replaced. I figure if the alternator was going out there would be 1) a warning message and 2) the battery would have died on me.
Do I have to buy a special battery? Do I have to go to a dealer to have the battery synced?
My other issue is with the heater. I tested it and it blew normal air. I tested again later and it blew hot air for a second but then returned to cool air I also turned the heater on and grabbed the 2 hoses that go into the firewall. They were warm, but that may just be from the engine heat?
From what I read so far it seems there is an electronic door inside of the dash that controls the flow of hot air to the vents. Could someone please elaborate further? I am a n00b to Volvos.
