Been having an issue with my A/C at low speeds and idle. I notice my car runs really rough at stop signs with AC on sometimes feels like its about to break down. When this happens it blows the J30 fuse for the Radiator Fan and then my AC will not blow cold air. Ive replaced the fuse and relay a few times and it doesn't do the trick. I've also replaced the radiator fan and shroud. Has anyone run into this issue? I'm driving a 2011 Cruze 1LT 1.4 Turbo

Edit:MOD can you move this to GEN 1 Powertrain? I had too may tabs open :( My apologies

I have had the check electrical system screen randomly pop up a few times. Lights have dimmed in and out while driving but that hasn't been happening recently. I did look at that sticky about the cable but haven't had any of those symptoms.

When I get a chance, I'll have to look up J30. Too much current is a major clue. My first thought was bad fan, but it seems you've replaced it already.
Yes I did unfortunately. The day after i threw away the other fan I found out it wasn't the issue. My gut is telling me that the AC condenser is bad and is shorting out the system. When in idle it feels like the compressor is engaging and then the car shakes a bit and can hear the fan blowing real loud like a get engine for a few seconds.

Shop update:

So took it into the shop today and they said the pressure switch is needing to be replaced. It's causing the fan to go on and off instead of running consistently to keep engine cool. He is thinking when the fan kicks on hard like that its causing the fuse to blow. He also said one of the spark plug wires were loose making the car run a bit rough.

Once I get my car back I'll confirm if that fixed my issues.

UPDATE:

After all the work is done the AC was still not working correctly. It turns out that a diode on the replacement fan was not working correctly which controlled the fan while the AC was on. Since it wasn't working the fan was coming on real loud for a few seconds and turning off. Napa Auto Parts warrantied it and got me a new one and it's finally out of the shop and running great again.

So in the end it was the replacement fan and probably a loose spark plug cable causing all my issues.
