Last year I noticed that the A/C only worked intermittently in my 2001 Grand Cherokee Ltd. Sometimes if you turned the car off for a little while it would then work the next time you started the car.
I called a service writer and they told me it was some type of electronic component that would need to be replaced. By waiting it was like rebooting a computer or something. Now that spring has sprung the problem needs to get fixed. It seems like now, it's not coming on at all.
Sound like a common problem?
