So, the servo seems to be leaking coolant.

This is on a 100% working ACC-II system (yes, it is possible). Servo still works fine, Ask for heat, get heat. Ask for cold, get cold. Vacuum tight as a drum. All pods A-OK. Etc.

Frustrating, especially since most have so-so results with reman units.

Consensus? Aluminum body reman ($450)? Unwired Tools digital replacement ($700)? Will I get lucky and find that I only need heater hoses ($20)?

Grrrr ....

From the looks of the picture, you may get lucky. I would expect to see the body all wet, but it's over by that hose.

 

[hornetball]

That's definitely step 1. Here's keeping my fingers crossed. It's really hard to say until you get in there.

 

[hornetball]

Well, my luck remains unchanged. Which means, of course, it's the servo.

You guys do remans or the Unwired Tools stuff? Can the servo be serviced? It looks more like a leaking gasket of some sort than a cracked body -- although I haven't pulled it out yet -- just replaced the heater hose.

Funny thing happened at the gas station. I've got the hood popped and am contemplating the puddle of green liquid. Nice older guy walks over (i.e., about my age). Says he used to have one and it was the most reliable car he ever owned. Made me feel bad for the guy -- he must be driving some horrendously unreliable "stuff." Told him he owed it to himself to get a Mazda Miata. That really confused him.

Speaking of which, I think I'll drive the Turbo Miata to work tomorrow. It's a lot of fun. Even though its horsepower is double over stock, it never breaks. Ever.

Ahhhh . . . fine German engineering:

Killed a perfectly good battery too. Nothing self-destructs with more collateral damage than German stuff.

Here's the replacement. Hope it lasts. Has a one year warranty.

So . . . .:

ACC II Servo: $450
New Battery: $110
Wife Cruising Topless: Priceless

That's actually Chrysler spawn that MB elected to adopt...

 

[rs899]

Bad decision, as was MB's later one to grab the rest of Chrysler.

Wouldn't then there be plenty a Chrysler spareparts that may be canibalised partially or fully for the said AAC unit?

 

[rs899]

^^ No, not really because Chrysler realized how bad (?) a design it was much earlier than MB. I don't think there was any new Chrysler production past the mid 70s, yet it was used by MB as late as '81. There are a lot more MBs kicking around of that vintage than Chryslers.

Those of you who have them might be able to pick up some nuggets of wisdom from the Imperial club:

Ah, stop complaining about the part breaking and German engineering. The part is 31 years old. How many non German 31 year old cars do you see driving around anyway?

 

[cottagstan]

Uhh...wife cruising topless? Does that mean the convertible top is down?

You mean like this one?

 

[hornetball]

All better. Took the opportunity to do some cleanup while I was at it. :thumbsup:

 

[hornetball]

Correction. Not all better. Servo seems to be stuck. All I get is heat, and I do mean HOT!!

Here's hoping the warranty is worth a darn.

Should have done the Unwired Tools kit.

Someone who knows for sure should probably chime in soon, but I seem to remember reading something about when the servo fails, it also has a pretty good chance of whacking the amplifier (controller). Something about excess current draws due to the seized servo.

But that's only from a third-hand at best source.

[hornetball]

OK, I'm cooling off a bit (literally and figuratively).

I do think you're right about the above. However, the servo I removed was still working (I think), just leaking. Still, worth checking.

The other thing I just remembered is that the thumbwheel is adjustable and might need to be tuned to the new circuitry in the replacement servo. It's just a big, analog control circuit after all.

Here's hoping!! Back to the books (sigh).

If your servo killed the battery it probably killed the amplifier. Over the years that seems to have been the usual scenario.

 

[hornetball]

Will advise. Actually have a spare amp, so that would be nice. Could it be that easy?
