Hello everyone I'm new here, this is my first pick up(03 4.7 slt crew cab) I had an 04 duramgo hemI prior to this as my bad weather car since my g8 does fair to well in rain or snow. Anyway I been lurking on this forum since I got the truck two wks ago and have learned a lot about the truck and have done a few diy mods already. Anyway my issue is this, when I'm driving ac blows somewhat cold at a stop nothing but warm air. I did some reading on here and learned about the condenser fan being suspect and to try to give it a tap w a hammer. Well since mine wasn't turning I gave it a shot and it turned right on. But every time I shut ac off or car it would need to be hit again. So I know that's one issue. But when I hit the fan and it's running the air still isn't to cold. It's colder than it was but over time it gets warm(I checked and the fan is still running) I also noticed that the recirculaton position doesn't change the force of the air at all?.. On 3 my blower is kinda queit but at 4 it's loud. So before I go buying a fan and possibly a heater box is there any info anyone has that I could also check out? I put the ac gauges to it. It has normal pressure in both lines so I don't believe there is any leaks. Any insight is appreciated thanks.
