i have had a Viair450 for almost a year now with no problems until now. Here's the story: with it being winter here in chicago i rarely hit switches but the other day i was just messing around hit a few sides and didnt here my compressor turn on. :wtf: so I thought maybe it was just the relay, since that was the problem last time. I changed the relay, still no luck, i checked all the connections and everything is fine. I also checked the fuse and it's good. Is there anything that i am missing to check?? :twak: I guess if i've looked over everything I'm going to have to be in the market for a new one, so any input on the best price is appreciated. Thanks!
