Greetings.
While driving the 89 with either or both windows down partially or completley, the console becomes VERY warm with hot air coming from within it. Even if you have the temp adjusted to 60 and the windows cracked just a little, the hot air comes. With the windows completely up, it stays cool as normal. I have replace the HVAC programmer and the problem still persists. I believe the HVAC is working properly. The airflow/direction for the HVAC does change on demand as expected as does the temperature. No matter how you adjust the electronic climate control.... if the windows allow for air passage, the hot air ROLLS out of the console. Any ideas?
Try checking the seals under the console, where the shift cable/linkage comes through the floor. I bet one of them is torn or displaced. Air cant really come in if the car is sealed but when you open the window it lets the air flow through.
Driving with the windows down causes a slight vacuum inside the car which pulls air through the heating/ac vents and in the summer the engine heat and sunlight warms the air intake at the base of the windshield and the firewall including the evaporator core which warms the air. If you select ,"off", the doors should shut cutting off air through the vents and the source of hot air. If it doesn't , then you need to look at the doors and the vacuum system that operate them.
I have selected the OFF button and no air has been coming from the ducts in the dash, however, the hot air has continued from the console area. I currently have the car apart and so far..... the only thing visible as a potential problem, is the rubber boot under the leather boot does not fit suggly inside the cavity, I can see daylight in one area around it. Maybe as much as a quarter inch gap. I dont know if this is enuff to justify all the hot air traveling thru or not.
OK, I had the car apart today and looked for anything. I found only the rubber shifter boot I mentioned in an earlier post. Upon reassembly, I positioned the rubber boot on the outside of the ridge atop of the tranny hump. I will take'r for a run up the Interstate in the morning and see if there is a change.
Got the front and rear weatherstrip installed while I had everything apart. Not too tuff of a job, as is stated in earlier posts.... dont get in a hurry and everything will be fine.
