one or both problems
just low enough to cool driving and/or the cooling fan isn't working ,
some cars/trucks have a fan on the coil out in front.
don't get one of the cheap fill kits freon can be nasty to your body if a hose burst
a tech with gauges can tell the problem real quick .


ps with it idling with ac on see if the ac comp clutch is cycling both problems stated above can cause it to . if no elec. fans and cooling fan on water pump is pulling air thru the red. it prob is just low gauges tell fast jim
