| Frustrated with A/C problem
I have a 2007 GL450, and I have had ongoing A/C problems since buying it. IF it's hot outside, it can take up to 20 or 30 minutes for cool air to come out of the vents. I have owned many cars, and I have never experienced anything like this. I have mentioned this problem 3 times to the dealer over the last 2 years, and it never gets fixed. Has anyone else experienced this? It's become unbearable to the point where I think I might sell it. |
