Hey guys

My 99 Expy is not blowing cold air.

I have the can of coolant but can't seem to find the low pressure side to plug it into.

A little help please?

Thanks in advance

Thanks for all the help guys



If you want to know it is on the firewall under a wiring harness the is a real pain in the ass to remove.

Look for the starting solenoid and it is under that.

You have to unplug a sensor with two wires and then unscrew the sensor to get to it.

Just so's you know
