First day using the heater, but heater only blowing warm/cold air on max
Hi all,
As the title suggests, today is probably the first day of the year that the heater of my 330Ci has been used. Before I bought it, it had been garage-kept as winter started. My heater, however, did not blow any hot air for a while. It got a bit warm in the center two vents but the drivers side vent remained cold. I also turned it off for about five minutes, and turned it back on to the same results.
I also noticed that upon acceleration on the highway, the center vent air flow went a bit cold as well.
Here is some further information,
-The car has about 96,000 miles on it, I have put on about 4000 since I bought it in June.
-I had the AC gas recharged in June.
-Recently, whenever I would turn on and off the a/c maybe a few weeks ago, I noticed a slight crackling noice, like paper unfolding near the front where the windshield is around. I don't suppose that is too much.
-When I turned on the heater, I had it at max 91 degrees, gradually increasing fan speed. Is it bad that I immediately went to 91?
-On the highway, when I noticed the center vents go cold, I was accelerating from about 40 to 55mph.
I can only assume the heater works well, since the car lived most of its life in Toronto. Any help and/or input would be greatly appreciated!
