Good day all. Hoping y'all can help with an issue I am having. I am overseas in Italy with the Navy and purchased a 2008 Honda Jazz as my Naples beater. Recently i noticed that when I turned on the car the AC would make a loud fluttering sound, almost like it sucked a leaf up and it was stuck it the motor. The first time it only lasted about 15 seconds then quit on its own. The second time I changed the fan speed from low to max, it made the sound for around 5 seconds then quit. I lowered the speed back down and all was good. The final time, I started the car, the fan speed was low, I changed it to high, it made the sound for 30 seconds then the whole blower system shut off. The 3 times were in succession of each other.

I did some research and found out about the blower motor and resistor issues. I figured it was not the resistor because the system does not circulate at any fan speed, it's just dead, so i bought a new motor. I replaced it and checked all the connectors with no visible issues found and it still does not work. I did the idiot check on all the fuses and found nothing blown. I pulled the resistor and took the cover off to check the solder connections and did not see any issues. I do not think the control switches are the issue because they function normally according to display, and the sound that was being emitted was from the passenger side where the motor is.

If anyone can provide some guidance as to other possible issues, or if they have had a similar issue, I'd greatly appreciate it. I know it could be the compressor, which I haven't really investigated yet and I'm hoping is not he problem, but I don't know where else to look.

 

Compressor issues won't cause the electrical blower motor to stop working

1. Check for power at blower motor plug.
If no power,
2. Check for power on resistor plug (these two could be switched my ALLDATA is in my car outside).
If no power,
3. Check for power at fuse box for BM.
If no power,
4. Check for power coming from CC unit, and check all ground locations as well. That will by process of elimination rule everything out. It's possible it backfed into the CCM, not sure how they're engineered on 1st gens and burned something up, especially considering the load was much higher due to whatever blockage got the other one seemingly stuck. I'm assuming there was some blockage which you removed.... Maybe some burned electronic scent from the motor... Telling...

If that is the case as a side example this actually just happened with a 2012 Toureg? van where the low speed radiator fan failed, backfed into the TIPM and ruined the low speed fan control circuit in the TIPM itself. Yours would be into the CCM circuit. Good luck let us know how you make out. Pröst!

 

Thank you so much for the reply. I replaced the resistor I had on order, which did not help, but I did end up finding some additional issues which may be the main culprit. I inspected the compressor clutch to make sure it was free spinning, no issue there. But then I noticed the compressor fan was not turning on with the compressor. Then I noticed that the radiator fan was also not engaging. I double checked all the fuses, still good. I then found the relay box that houses the radiator, compressor clutch, and blower relays. I did the idiot checks on those by pulling them out, reinstalling them, tapping them lightly, didn't fix the problem. I doubt those are connected in parallel, but it seems odd that all three are bad, so next I'm testing the connection board to make sure it is sending power. I do know the AC is driven by a computer, so if there are any error codes from the computer, the AC could shut off. But I don't have any warning lights or codes coming up. If anyone has any ideas, I'm all ears. I'll update this post if I figure something out.

 

From my experience:

1) if your system is low, there is a pressure switch that will prevent the compressor from engaging. I’ve heard this switch can also go bad.
2) I refilled my system with 134A and my compressor started engaging but it would blow the fuse.
3) I found that the compressor clutch magnet was bad, ended up replacing that but after multiple changing out of the compressor clutch plate, I sheared off the stud on the compressor shaft (I know, not my proudest moment, should bought the special clutch holding tool).
4) replaced the compressor with a UAC branded unit, refilled and it worked.
