Thanks all for the info (resistor and test info especially). As soon as the weather clears, I am going to check the system out. How much of a job is it to replace the resistor?

On this set up both speeds use a relay. Low speed is on the fuse box. High speed is above the fuse box under the dash. It gets a fusible link and a separate supply wire from the battery. The AC system should operate the fan also on a low speed anytime the compressor is running. If it does not along with the radiator not turning it on the resistor is the common problem. Also there is a 30 amp fuse for fan controls and low speed. <BR><BR><BR><BR>Dennis<BR><BR><BR><BR>From: Vanagon Mailing List [<A class=parsedLinkparsedEmail href="mailto:vanagon@gerry.vanagon.com" target=_blank>mailto:vanagon@gerry.vanagon.com</A>] On Behalf Of David Bjorkman<BR>Sent: Tuesday, September 18, 2012 3:30 PM<BR>To: <A class=parsedEmailparsedEmail href="mailto:vanagon@GERRY.VANAGON.COM" target=_blank>vanagon@GERRY.VANAGON.COM</A><BR>Subject: Radiator thermo switch<BR><BR><BR><BR>Hi Volks;<BR><BR>All of a sudden, my radiator fan only works on high. I was driving slowly in traffic, with the A/C on . My lovely wife looks over and says "Gee, I've never seen the temp guage that high". Holy smokes, I look down and the needle is at least a full needle width above the LED (Inline 4 FAS motor-cast iron -:)). Even in Mesa, AZ this past June at 110+ F with the A/C on I have never seen it that high. I wasn't even sure the gage itself would go that high. Well, just at that point the high fan kicked in. As I thought about it, I had only heard the fan kick in (I usually kinda note those things as past esperience is a harsh teacher) on high at all that afternoon. I have heard that A/C has some sort of a high fan kickin, althouht I am not sure how to tell the thermo switch high fan from the A/C high fan, if there is one, so I am not sure if the thermo switch was working at all, but the fan sure was. I took the bus onto a street where I could travel at 30-40 MPH and it cooled right down to just below mid LED, where it usually runs. <BR><BR>Anyway, unless someone thinks otherwise and can enlighten me, I am assuming it is the radiator thermo switch. Haven't looked yet, but can I trust a FLAPS switch (if avaliable, to save me a wait for the mail), or should I go right to one of our friendlu, helpful vendors?<BR><BR><BR><BR>Dave B.<BR><BR>'87 Westy w/FASTT inline 4<BR><BR>'84 Westy WBX<BR></DIV></DIV><BR></div>
