This weekend, I drove my '97 LX (with 285k miles) about 1900 miles and noticed a strange issue with the A/C. On my normal commute (rush hour, stop and go, etc) , in the afternoon sun and 97 degrees, I keep the thermostat on the A/C above 65 degrees, otherwise, the A/C is uncomfortably cold.
However, returning home this weekend, after driving for 7 hours or so at 75ish, the AC started to get uncomfortably warm, even though it was sunny and 83 degrees. The air coming out of the vents was definitely colder than ambient, but I had the AC on full cold max fan and it wasn't cooling that well. We stopped for a break for maybe 30 minutes and after the break, the AC cooled much better.
Any thoughts on where to look? I guess I need to start with checking the A/C coolant pressure to make sure it's up to spec.
thanks,
