A car blowing cold air only while driving usually means:
Low coolant level – not enough heat at idle
Air trapped in system – blocks heater flow
Weak/bad water pump – works better at higher RPM
Partially clogged heater core – needs more flow to heat
When you drive, coolant moves faster, so you finally get heat.
