I noticed that my a/c wasn't working to it's full potential. When the car is idling, even for a brief second at a stop light, the vents would blow warmer air. I hadn't had a recharge in a while and figured I was low on refrigerant. I bought a can and when I was filling it up, I noticed my condenser was clicked off for about 2 seconds, clicked on for 1 second, and clicked back off and it did this until I turned my car off. While it was clicking, I noticed a small spark in the fuse box. I then proceeded to use a paper clip to relay the clutch thinking that I was so low on refrigerant that it wasn't even registering.

After trying that, the condenser won't turn on at all now, my vents are only blowing warm air. To top it off, my Check VSC, traction, and check engine light are all illuminated.

Hoping someone out there has any solutions or suggestions before I take my 07 is250 to the dealership and fork over my savings account.

 

You probably blown a fuse somewhere. Look at all fuses first. If all fuses are fine, try the ecu reset.

 

Fuses look good. Tried the reset a couple times. Also tried tightening the gas cap. Dash is still lit up like a Christmas tree. However, seems the condenser has clicked on, the air coming out of the vents feel pretty cold but it's still morning and relatively cool right now.

 

If anything, start by doing a full system reset by disconnecting the battery for 15 minutes. Then reconnect, and drive it like you normally would. Hope the A/C comes back; I know I cannot live without it here in SC!

 

I actually just now replaced the battery and the lights are still on.

Ran diagnostic too and it's pulling faulty sensors. One of the sensors it's referencing was replaced less than 2 years ago.

Air conditioning still not working. Condenser isn't even turning on so I can't put more refrigerant in.

 

what are the codes?
