yep most likely the fan is not coming on, or not coming on soon enough
there are two fan speed settings, hi and low, which kick on at a defined temperature which can be adjusted in the tune -- so if you installed a new tune shortly before this started happening, that could be the cause (but most tunes turn them on sooner rather than later) otherwise it is probably the relay, if I remember correctly from other threads I have seen on here -- you should be able to find them, with the details, using "search" feature one quick and easy way to test: turn on the A/C; the fan should come on when the A/C is on . . . if you let it idle with the hood open it could take a while but that is the best test |
