check to see if your blend door is moving from warm to cool when you move your temp knob.

what the blend door?.......all the functions work from defrost to the vents at the feet .......and when i turn the temp up it does get hotter .....so thats working ......its just at coolest setting and on max ac it blows warm

IT depends on how long the cycling how long is the cycle if it is repeadly very quick you prob have lost a your R-134A charge and therefore have a leak in the system and will have to leak tested
