Hello. My 2007 V70 2.5T has developed a smell when using the heater.
It does not smell like coolant, and not really like oil or exhaust either. It was very bad for a few days, basically rendering the car unusable, but now has subsided somewhat but still there. If I had to characterize it, I'd say it is like the smell of electronic components burning. I smell nothing unusual under the hood, and the heater fan and rest of he car performs normally. It has 58k miles. Any ideas? Tia
