My A/C is blowing hot air but if i turn it to Lo and put the fan up all the way it will blow warm air for about 30sec-2min and then it will slow down and sound like a baffle will be pushed over and then it blows really cold..any thoughts on whats wrong? Do i just need to recharge it or is there a bigger problem

 

Soiunds like sticking flap valves. Find someone with a vagcom and check for codes in the HVAC system, and run system diagnostics.
