A/C sticker shock

Tue Jul 10, 2018 2:30 pm

5 months in to owning and loving my little "Evie" I got the dreaded RBS, exclamation point warning lights on the dash.

Car towed to dealer.

Dealer says its an internal A/C issue, looking at over $3500 to replace the A/C compressor.

Any suggestions?

Anybody need a parts car?

Sure, I'm wanting a black parts car- I see you're in Chicago?
BUT, I'm suspicious of that diagnosis. A failed air conditioning compressor shouldn't be a no-run condition. Please post as many details as you can, such as did it actually shut down or is driveable, but with warning lights, and whether it will recharge with J1772 or CHAdeMO.

Driving to work last week I felt the power cut off, go pedal went to the floor, i was poking along, loss of braking, warning lights went on RBS, !, turtle and just a RED battery, ready light turned off. Cycled the key a few times and it got me the 3 miles to work.

While running an errand the same sequence happened again, and again, and again.

Limped it home, barely made it up the slight hill into the garage.

Checked the FORUM, replaced the 12V battery.

Turn the key, READY light, YAY its fixed....7 seconds later same series of warning lights.

Also car would not take a charge from home charger.

Next morning went out to car, it went into READY mode, i was able to drive it up and back a bit, put it on charger and went about my morning routine'

4 hours later, unplugged her, READY mode just fine, within a 1/2 mile same sequence of events.

Limped it home and called AAA for a free tow.

Did you measure/charge the new 12 volt battery before installation to make sure it was a good one?

Did you ever get a chance to charge up the pack to full (16 bars)?

Was the fuel gauge indicating full after letting it connect on the charger until it cut off on it's own? If it was showing less than 16 bars then there could be a bad cell in the pack.

I am frustrated as heck over this situation, and my wife is ready to kill me over my "wise" purchase.

when I charged the car that morning it was for only about 4 hours, went from 17 to 30 on the guessometer.

upon further review, there were times when it went into default mode and the ready light stayed on, and other times the 12v battery light came on.

dealer ran all the diagnostics and all that showed up was the AC compressor fault. I'll get a full list tomorrow.

if i only charge the car on 120V home charger and the battery is passively cooled can it be safely run/charged?
would disconnecting the A/C have any effect on the heater?
i live on the southern tip of lake michigan so heat is a necessity, i can always open the windows for a breeze.
Bear in mind I only drive @12 miles per day.

i think another member just disconnected the big orange HV wires to the A/C and was able to operate just fine. Level 3 Chademo charging uses the AC, so that would not be possible, but regular 120 or 240vac (lvl 1,2) should work just fine.

Seems like the dealer didn't want to disconnect it, but you could charge the car at the dealers, then take it home and diy.

Somebody who did this should chime in and set me straight if i got this wrong.

I think I shorted out the dealership.

I asked if
A) the A/C compressor could be disconnected
B) if they could do it
That was 5 hours ago and haven't heard back from them yet.

I'd sure like to know what goes wrong with these compressors.

I don't know what disconnecting it would do, but I do know that the A/C is totally separate from the heater, so being without A/C shouldn't affect heat. Without the compressor, DC quick charging may be possible, though it'll likely fault if the battery is warm and the car calls for cooling. The battery fan always runs when charging at a high rate below 60% charge. I don't believe the car does any active battery cooling while driving.

Thanks.

I'm not sure about a non-working compressor. But when I had a faulty A/C fan motor, the cooling would stop after some seconds of starting a QC. But I still managed to make two Chademo chargers until I reached home, without the A/C running. Things got quite hot in the battery, but otherwise charged fine.
