Hello,

While driving down the road my A/C starts blowing warm air, after a while it will start blowing cold air again.
A local mechanic said that it had freon and he couldn't see any issue? Please Help.

Could be feezing up blocking the orifice tube, low pressure switch, temperature sensor and AC control module.

Check the compressor clutch clearance. Spec is 0.3mm to 0.5mm Very common for this to wear down. Always replace them for that reason.
