On the electrical, I refer to my air conditioning and heater. When I have my air selection to coldest and I drop 1 click for it to be less cool, my heater turns on and at times it smells like something burning. I have to turn it off . On the engine, after I hit 90,000 miles, I have to fill up my engine oil every 2-3 weeks because my vehicle is burning it quick or something. It dsn’t leak oil at all. The oil just seems like it’s burning somewhere and I ha e to be waisting money to buy oil $30 to $60 a month. Please help. Thank you!
