there is a similar situation with my car the heater is not working in passenger side. had replaced the ac which i bought it from scrap yard wasent very expensive.
cadillac is one of the high maintenance cars yes and the resale is not very good yes
but when you drive a cadillac you feel like you are the king of the word YES
so to have that feeling i dont mind the cost.
i had to get mine changed which the mechanic had taken a day and mine was the only car he had to work on i wonder if it was 3 to 4 hours work why did this happen.
