Hi gang, haven't been on here in quite a while (and I mostly just lurk...). My '04 TJ Unlimited has developed a problem with the heat/a/c fan. When I bought it a year ago, the lower middle speed setting didn't work. No big deal, I didn't really need it. Now the only setting that works is full blast. While that's not usually a problem for me, I think my girlfriend would appreciate some relief from the arctic conditions. Someone suggested it was the a/c relay in the fuse panel, but I'm not sure. If it's the fan only, would that be the a/c relay's fault? Is there a separate fan relay, or some other control device to replace? Any help or suggestions would be greatly appreciated.
