Well, I didn't want to pollute this thread with all my other issues. I have codes from everywhere. I have the dash apart, battery removed, new fans ordered.... The A/C was the least of my concerns so I just got around to checking the fuses. I don't like that the fuse blew at all but... I will investigate further. I just want to be comfortable when I reassemble that I have sufficiently looked at root causes. You have a great thread here Dan and many of us appreciate the time you take to respond.
Question... my radiator temp reads open on all the wires and no contact with any to ground. Is that normal. Temp outside was 85 degrees and the car had not run in a few days so... I am confident the radiator was about ambient temp.
What makes the 7.5 amp fuse blow ? 2006. Could it just have been an electrical surge or something. Perhaps the A/C clutch is going out. Yes yes... I will check the ohm reading. LOL I'm just snowed under with all this. I will laugh at myself if this was the main issue... da fuse. Ha ha. I hope that is all it is but....
I got brake a light on the dash and no communication with the airbag... LOL and parts to this car everywhere. I needed PM anyway so I'm good. Thanks again for all your help.

What brand compressor did you get? And that's luck on what fixed your issue. I got the short straw and needed a new evaporator.

Other than hoses my whole ac system is new now. Condenser leaked a little and when the clutch got done it finished it off. Most of my parts are all denso brand including the condenser

I almost purchased Denso but didn't. I did a good bit of research and ended up purchasing UAC. I had to say a Hail Mary when I bought it because Amazon said it wouldn't fit my car but my research said otherwise. It fit great an I am happy with it. Glad I found this thread as mentioned, I had cooling fan issues as well. Good Stuff !!

I'm having a really strange problem discussed here, please advise anyone! I will be working on it tonight. Why do I always get the complex ones. I have the A4 fan and AC troubleshooting guides. The AC trouble shooting one is well done! With the duty cycles and such. I'll see what I can find tonight, thanks

Here is a perspective on that. You get the complex problems because you can solve all the rest... so the only problems you really have are complex ones. LOL Pat yourself on the back.

Does anyone have any input on why one radiator cooling fan would work and the other not until I spin it by hand. Problem is rather new to me. Thanks in advance.

Not uncommon; replace the bad fan! Right now it won't kill you one way or the other but it does very ugly things to the load on your A/C system to not have both working properly.

I'm just seeing a weird fluctuation of my temperature, so I didn't know if it's something I should worry about

Check the other sensor with VCDS (there are *two* sensors in the CTS; one feeds the ECU, the other the cluster.) If the one you see with VCDS doesn't show a problem them the sensor is probably bad; they have a habit of going sideways every few years (or the O-ring seal starts leaking!) but the good news is that they're reasonably cheap.

No VCDS needed, just replace or refresh fan if it's bad. If engine temps are the issue, try a better thread, this one is for AC related issues.

Still trying to get used to the site and finding things. Was having issues with unusual rising engine temperatures. Can anyone point me in the right direction?
