The FanZilla will only report a problem if one of its fuses blows. If the wiring goes open circuit, it will not detect this. The next step is to see if there's 12v on both Fan outputs when it's on. If there is, then you know it's wiring, if there isn't, you know it's the Zilla. Martin Steven L. Alves wrote: >I have been having a problem with the AC not blowing as cold as it used to. During troubleshooting I found one of the cooling fans (left one) is not coming on. I metered it at the fan connection and there was no voltage. I popped the electronics bay cover and examined the 2 fuses on the fanzilla and they are both good. I even tried switching them. Do fanzillas go bad? What do I trouble shoot next? > > >Steve >#2700 > > To address comments privately to the moderating team, please address: moderators@xxxxxxxxxxx For more info on the list, tech articles, cars for sale see www.dmcnews.com To search the archives or view files, log in at http://groups.yahoo.com/group/dmcnews Yahoo!
