A/C heating vent question.
On my 95 LS that I sold and on my current 98 GSR, whenever I have just the vent open and set to the max cold setting, it blows in warm air. Why? Is this because I changed the stock air filter to a SRI? This was done on both cars. Or is this some other problem?
Now my GF's stock Civic 2004 will blow in cool air when set to max cold.
