07 350z AC/Heat Intermittent
I'm trouble shooting my 2007 350z ac and here is what's happening. When I have the vehicle on, I turn the knob to any blower level and get nothing to happen. I press the AC button and i hear it engage on the AC clutch mechanism and I feel the vehicle working harder. Neither the cold or hot turn on initially but after 10-20 minutes driving the blower kicks on. The cold and hot at that time work fine but if I shut it off, there is a good chance it won't come back on.
I checked my low pressure freon with a kit and made sure it's serviced, which it is. I was looking into the FSM and the schematics but it doesn't look like the 2007 had a blower relay or I would replace that.
This all started two years ago but in the beginning it was rare that it wouldn't turn on and it would turn on faster after not initially starting, within 2 minutes. So over time it's gotten worse, any ideas? Thanks.
