A/C only blows cold while driving

#45 if electric fans it gets more tricky, computer controlled? or trinary or binary switch in the mix? Is the signal for A/C on good? power through switch? Fuse good? good connection as well? Relay working properly?trinary or binary switch coming on at proper pressure? does A/C have separate controller?wire pinched? or a short in wire? either control or fan power? one simply issue is not always so simple as more and more computer controls are introduced

 

When tracking down electrical issues you can have proper voltage and NOT proper amperage in high amp draw situations.
