I put freon in my buick park avenue and it only took a lil bit and is still blow hot

Buick park avenue blows hot on driver side

The mode door is stuck for passenger control.

i just bought a 98 park ave and i had the iossue of hot on passenger side and cold out the driv ers i was told i had to replace the control head and both accuators...... i did a trani flush and it fixe my problem

don't know if it makes sense but my 97 park avenue did the same thing. all i did was to pull the system completely down with a vaccum pump and recharged it with freon and it now works
perfectly. like i said it don't really make sense but it worked!!

It is most likely low on freon,not much ,just a little,just add about a can.

Make sure there are no leaks and that the system is full to capacity. After the vehicle has warmed up check radiator hoses for temperature differecial also check heater core hoses. A significant difference in temperature may indicate a plugged heater core or thermostat failure

check the freon level, also check to make sure that the a/c vents door are not jammed

Most likely a blend door issue inside the dash or a problem with the HVAC Control head.Hope this helps!!

Try putting in a.c. leak detector first to pinpoint where the leak is coming from...That can be a costly repair if you take it to a shop especially if you can't find the leak yourself !! Well best of luck..hope this was helpful
