1997 Buick Skylark Questions & Answers
I ran the air conditioner yesterday and everything was fine, when i got in this morning, it was cool so i turned into vent and moved the thermostat to red. This afternoon it was warm so moved it back
I'd probably check the blend door under the dash for proper operation. Sorry, I don't have any pictures. Also, if the blend door is vacuum operated, check the vacuum. I did check hvac wiring diagram, didn't show any actuators, so, I believe vacuum operated. I'd have to look at it, to diagnose further, sorry I don't have better info.
Make sure it is full of refrigerant and compressor clutch in engaging.
97 buick skylark ac evaporator core what do i need to do to get to it
Did you replace the schrader valves (the thing in the inside of the A/C service fittings, you need a special tool to remove and install them) before you recharged the system? They are notorious for leaking if they are old.
If you did not, replace those and try again, if it leaks out again with no evidence you most likely have a bad evap core.
And yes, it's a pain in the ****, plan on it taking a 30 pack of bud light and a weekend to do, or one day and a 12 pack if you are good. Just start taking the dash apart, and may the force be with you. It will be behind the glove box
