A/c problems w/ 2005 Grand Cherokee ltd.
Two months ago I had to take my Jeep for a tech bulletin computer update at the dealer. While there, I had an actuator replaced that operates the drivers side air vents due to a ratcheting noise when changing from outside to cabin circulation. Other than that, the a/c was working fine blowing cold air.
After three hours, the service rep tells me that I was low on freon and that the tech installed one pound of freon and one pound of dye. No charge to me because while doing so, he broke the Schrader valve by accident. On the drive home, the darn air vents still did not work correctly, so I returned to the dealer and now I needed another actuator the tech missed. Six hundred bucks later I am out the door.
A few days later I started smelling a very bad freon odor whenever I used the outside circulation setting, but it cleared up once switched over to the a/c setting. I figured the tech had some how gotten freon in to the cabin air intake. So, for a few weeks I kept the fan on high while driving with the windows open hoping the smell would disappear. Once the smell disappeared, I would switch over to the a/c and close the windows.
Since that didn't solve the problem, I popped the hood and removed the cabin air filter and cleaned the intake. Still no go. Took the Jeep back to the dealer and now the service writer says I have a leak and will need a evap core due to finding a leak on the edges of the heat shield on the evap drain. Plus they have to order the part and it will cost me $1800 and they will have to r&r the dash.
I now have an appointment with a local repair shop to see what they find. I certainly can't drive the vehicle with this smell since it is not healthy, but the a/c does blow cold air. I can't understand why the a/c works perfectly if I have a month old leak.
