There are 3 things that could cause this. 1 A bad otterstadt switch or if you have the old style pipe, an air bubble. 2 A bad or old, undersize circuit breaker for the cooling fans. 3 A low charge of refrigerent in the A/C system For #1 To test it just jumper the 2 wires at the switch and see if that helps. For #2 Listen if it clicks when the fans go on and off. For #3 Does this happen if the A/C is off? If so then it is not the A/C. Since you say the A/C is not blowing cold my guess is that the quick-cycling only happens when the A/C is on and you need some refrigerent.

What gives wires seem fine and connections are tight, the same results @ higher R M P's too. New Alt. and the fan fix is installed for about 6 months with no problems until now. Except A/C stopped blowing cold at same time. > Any suggestions? > > > > [Non-text portions of this message have been removed] 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!
