Friday the 13th: wrecked W124 E320 Wagon

I noticed yesterday that the air out of my vents was not getting cold. When I got to my driveway, I restarted the car, and the AC came back.

No luck at all so far today. It takes a long time to switch from hot to cold, including an awkward period of warm air in the side vents and cooler air in the center vents.

I cannot hear the click of an AC compressor that I here so easily with my W123 and R107. Does the compressor audibly activate on a W124?

I see a heater valve on the passenger side of the engine bay behind the firewall, and am thinking that would be the likely culprit. The belts are all new within the past few months. Any suggestions? I hope its not a Friday the 13th situation and Jason has just put an ax in my Evaporator.

You can visually check the A/C compressor clutch while the engine is running. But most likely the A/C is low on refrig. That's usually caused by a leaking evaporator. Happy 13th.

Lots of potential culprits when the clutch will not engage.

Unlike the W123 cars, the W124 belt is a serpentine and MB has included a disable on the compressor clutch when the rpm of the compressor does not match the crankshaft. (clutch slip)

The RPM sensor is located on the back of the compressor.

You may also have a KLIMA relay problem, and I recall this is integrated into the OVP relay on late w124 chassis.

Could also have a bad pushbutton unit.

May be low on freon.

The factory manual has an extensive diagnostic section, which is most helpful on these cars. (Hint)

That chassis also has a high side Eye-sight on the reciever/drier...if clutch is pulling in, check the eye-sight for refrigerant flow......

Well, the AC came back on the next time I started it, and was working beautifully, then this Friday the 13th got worse.

Wrecked the car. I'm fine, but the Excelsior sure isn't. Not good.

Sorry to hear, hope it gets better.

How bad is it? Repairable? Everyone okay?

As long as you are OK

Everything else is replaceable.

Some road construction in the area made for some uneven roads. I probably wasn't gripping the wheel as hard as I should, hit a bump, and it cocked the steering wheel, sending the car in the concrete divide before I could recover. The bounce off the wall, and my overcorrecting, sent me into the ditch.

Not much cosmetic damage, but the check engine light, ASR, and ABS light were on. I know the ASR wasn't working, because the tires were slipping in the mud to get out of the ditch. I got to a safe place to pull over, the front right wheel bouncing and front end grinding all the while, and after a few minutes of idling, the temp. gauge shot up over 100 degrees. I shut it off and had it towed. I didn't see any fluid leaking, or any belts loose. I have comprehensive coverage on my insurance, but I'm worried about the mechanical issues.

I just put the wheels on 2 days ago too. I have barely left my bed since about 5:30, I'm very depressed.

From just standing looking at it....doesn't look like a lot of damage. Perhaps something (electrical) got bumped underneath causing all the warnings/malfunctions.......its good that you have the insurance, it will likely cover that stuff.

Hopefully the poor MB isn't too badly hurt!

Sounds like collision damage claim to me, not comprehensive.

I hated getting the text message yesterday from Tyler stating "Just wrecked the Excelsior". My mind started to picture the worst; car laying upside down in a ditch, or the front bumper slightly in front of the dash board.
I know he feels awful but it sure could have been allot worse. There is nothing more dangerous these days than construction zones, which are everywhere, and care is not always taken to make sure it is completely safe for motorists. So, if nothing else, the Excelsior will be repaired and restored to its former glory, and a life long practice by Tyler of watching for the worst in future construction zones will be utilized.
So, your one day of mourning is officially over. Now go walk that dog......

Fortunately from the photo, it is apparent that the fender and bumper have been replaced before, pretty crappy paint on the fender too.

Someone other than me might know if your LCA is replaceable with the earlier version, it is likely bent. The tie-rod possibly also, and your ASR problem is most likely due to an ABS sensor wire damage.

The wheel though, that's a shame. You'll need to assess the amount of damage, and if it is not much more than the deductible, it is often better to not claim it and risk increased insurance premiums (they always get their money back it seems, even tend to profit on a claim eventually).

Best of luck. I might have some used steering parts I can live without also, let me know.
