When I put my climate control to low. It blew Luke warm air at me.

Do I just need a re-gas?

The heat seems ok and it clears the front and rear screens very quickly. ?

 

could be anything, re gas, compressor, fuse.........

i'd worry about getting the head gasket sorted before worrying about the a/c

 

It's in the garage as we speak.

 

+1 to Police666 - what is the point of concerning yourself w/ air con when you might in fact have to replace the entire engine at a replacement cost of over $3K - if they pull the engine - they will disconnect the A/C lines anyway...
