[67malibu]

'99 malibu, 183k, no real issues. Did the fix on the A/C control head (cleaned the contacts) and it cooled good for a few days. Now, it won't cool a degree (and I mean not one degree) for at least 5 minutes after you engage the compressor. It would cool fine before the fix, when the compressor would be engaged. Now after about 5 minutes, you get maybe 15 degree drop, even at interstate speeds. The compressor is engaging and staying engaged (visibly confirmed), the heater damper is not stuck (confirmed visibly and when you turn to heat you get much hotter air), and it has 34 psi of freon on the low side, the same as it had a few weeks ago before the control head fix. Any ideas?
