I sure miss my 2 car garage with insulated door and window AC unit in the last house. I didn't have any windows in the old garage, so I installed the window unit in the back door.

Now they make portable A/C units, too. They're on wheels (thus portable) and about the size of a large window A/C turned on end. All you need to provide is an exhaust outlet about the size of a dryer vent. The better ones will evaporate their own condensate and blow it out with the exhaust air, so you don't even have to drain them. They're available up to about 12,000 BTUs and they're pretty effective. I've used them for cooling small server rooms and the like.

HAHAHAHA I have a 5000btu window AC in my 2 car garage! ;-) I have a disease (similar to MS) that disabled me in '99 - and the meds I take mae me sensitive to heat. My mother-in-law bought me a window unit because she knew how much I enjoyed messing with cars on the days I wasn't in pain and when it got too warm (70) I could only be out there for a few minutes at a time. Bless her heart - she stayed with us during her last years - a sweet lady. Anyway - the AC cools the garage down to ~70F even when it's pretty warm outside - today I'm replacing the alternator on the '91 300D and I turned it around this morning before it got hot outside - it's supposed to be close to 100 with 90%+ humidity - so I did't lose too much of the cool air. I have insulation and sheetrock on 2 walls - obviously can't do much more insulating on the big garage doors - but I have 1 more wall to do - which is shaded by trees so it's not too bad. Of course, I also have a fan to move the air around - whether the AC is on or not. I guess 'm spoiled. - Can't imagine how I made it when young - we didn;t have home AC until I was 12 or so - no AC in the cars either - this was early 60s - and it wasn;t unusual to have a car or house without AC IMHO. Anyway - ya'll stay cool - the east coast is supposed to have temps around 100F for the next few days. Check on the old folks - this is dangerous heat - I know ya'll in Nev get stuff hotter than this but it's unusual around here. ;-) Larry T (67 MGB, 74 911, 78 240D, 91 300D) www.youroil.net for Oil Analysis and Weber Parts Test Results http://members.rennlist.com/oil Weber Carb Info http://members.rennlist.com/webercarbs Porsche Road Test http://members.rennlist.com/roadtest/ . - Original Message - From: George Gregory [EMAIL PROTECTED] To: Mercedes Discussion List mercedes@okiebenz.com Sent: Sunday, July 30, 2006 3:35 PM Subject: Re: [MBZ] Aux Fan Craziness On 7/30/06 1:27 PM, Bob Rentfro [EMAIL PROTECTED] wrote: Even though I have an old oscillating fan movie air around it can't do much good unless you leave the door open for a spell.

A couple of times yesterday, when I started the car after it had set for a couple of hours and cooled off (well, relative for here) the fan came on when I turned the ignition switch.

Re: [MBZ] Aux Fan Craziness
The fan is operated via a relay. Said relay is activated by engine temp (switch is in the thermostat housing on your car) AND via a temperature switch on the receiver/dryer. The fan may be two speed, in which case there is a large ceramic resistor somewhere, and there will be two relays instead of one. You will have to check a wiring diagram to see for sure. Likely the relay (or relays) are bad or you have a worn or loose wire grounding. You can test the temperature switch wiring by pulling the connector off the switch in the thermostat housing and grounding it. Fan must come on in high speed. The AC wiring can be tested by jumping the wires on the temp switch (there are two switches, one for low pressure and the other for the fan), fan should come on in low speed if a two speed. I would look for worn or frayed wires first, as this is the most likely cause of goofy operation. Relays would be the second thing to look at (if they stick or fail to make contact). Switches can be bad, too. Peter

The engine temp was about 135 degrees F. Now, this fan should switch on at a prescribed temperature correct? And/Or should it be on when ever the AC is on? The usual cause of that is that the AC is on at start and the engine compartment has gotten a good heat soak, causing a high pressure in the AC system. It usually shuts off pretty soon as things stabilize. The aux fan is _not_ normally on all the time the AC is on, by design, and I'd agree with this. Because the AC compressor is on such a large percentage of the time, unless EC is selected, the aux fan would run too much. It's not rated for continuous duty, in that it'd wear out pretty quickly if it were on all the time. So it's wired to only come on when needed. -- Jim
Re: [MBZ] Aux Fan Craziness
Hi Bob, My 91 300D does that too - even when starting cold in the morning - turn key and wait for GPs, the fan comes on - startup - it eventually goes off. I've read Peters well written troubleshooting comments but have not gone looking for trouble as the fans works when it gets hot just like I want it to -- with temps in the upper 90s I had to idle for a few minutes - with the aux fans on the temp stayed at 80C - the temp of my thermostat. I was amazed at the capacity of the cooling system - AC running, at idle - and no rise in temp.

Re: [MBZ] Aux Fan Craziness
Nope...it's always on. I hope that the attic fan from my in-law's house is include in the stuff I get to schlep from IL to AZ in Sept. That pig could move some air. I would install it in my garage. Looking forward to looking off of the interstate and seeing new Busch Stadium as I pass through.
