SOURCE: saturn ac wont blow cold air
check cooling fan operation while ac on.If fan is working proper,will probably have stuck exspantion valve.
SOURCE: air condition blows hot air but it has freon
You may have created an over charged condition and at this point the a/c compressor will cut off on high head pressures. This can be verified by installing gauges to the systems high and low side service taps and reading the pressures.An overcharged system will start the compressor briefly but soon cuts off once pressure goes to 350 - 400 lbs on the high side. Acceptable pressures for this system should be no greater than 250 high and low suction should drop to 40-50 psi.You might recover the charge and evacuate the system,then try bringing the charge back to proper level.A sight glass in the reciever drier really helps determining proper fill.Once all bubbles have dissipated from the sight glass during charging ,one should stop at that point to avoid overfilling.Too much freon is worse than a low charge especially in hot ambient conditions....
SOURCE: remote start dont work in 2008 saturn vue and its
The hood latch has a switch in it. The hood latch does not move the entire distance when the hood is closed and the switch does not close so remote start will not work. Everthing else appears to be OK. I have had two hood latch replacements on my 2008.
