2000 Nissan Maxima GLE, 110K miles
About three months ago, I took this car on a 400 mile drive, halfway through the engine got pretty hot and the A/C started blowing out hot air for the remainder of the trip. We pulled over to buy gas and the A/C worked for about 5 minutes til the car got hot again. I got the radiator flushed and the engine never overheated again.
(Note: This trip was the first time I know of the car making a long drive in heat. It was 80-90F when it overheated the first time. I just got the car and had only driven it during winter with little A/C or with the heat on.)
After that, the A/C has been acting up. After about 200 miles of driving, the A/C will cycle between hot and cold air. 10 minutes hot, 10 minutes cold, repeat forever. In city driving, the A/C functions fine.
I took it to a mechanic, he ran the car for about three hours and found no problems.
I took it to another mechanic who ran the car for 15 minutes and told me I need a new condenser coil as mine has bent fins. He quote $500 parts + labor. Eek. Would a condenser coil match my issue?
I then took it to a Nissan dealer, who ran it for about 7 hours and found no problem other than the freon was a tiny bit low. He recharged it, but said nothing was wrong and that the freon probably wasn't the cause.
I do a lot of 400 mile driving in 100F heat, so I really want to get this fixed, but I don't want to waste $500 on something that might not be the problem. Its a pain because I can't recreate the error without going on a long drive.
