Anyone have problems with their A/C not blowing cold after installing e-fans? My A/C will blow 40* when I'm running down the highway, but when I'm stopped or driving slow (25mph), it warms up to 60*-80*. I installed a manual switch that turns on my second e-fan and that helps, but still doesn't get it down to 40* like driving does. It's a kit from a sponsor here so, it's not a cobbled together e-fan kit either.
