I'm trying to plan ahead for summer and things that I need to replace and repair on my 81 D. I live in Houston now (and used to MUCH cooler weather), so I'll be running the AC quite a lot. :) So, I've noticed the problem of when the compressor kicks on the engine drags and drops power. I know there is the FanZilla and the SpecialTauto fix for this. But bear with me for just a moment. I can hear relays clicking behind me, in the electrical compartment presumably, though I haven't checked into it too much. It kicks on every 5-10 seconds it seems. Is that normal? Or should I be doing the cooling fan cycling adjustment on the dryer assembly first, then the fanzilla? http://www.dmcnews.com/Techsection/aircondfancycle.html And, I don't want parts vendor war here, but what are the functional difference between the Zilla fan product and Herv's? Perhaps those replies should be made privately to me a dmc4687(at)mindspring.com. Thanks "Y'all"
