My 97 suburban blows cold under 60mph
My 97 suburban blows cold air unless I'm over
60mph, then it blows heat. As soon as I begin to
slow it blows cold again. As well, I noticed to
defrost only blows on the passenger side. To top it
all 9ff, the actual is no longer working.
Check the coolant level as it may be low.
