AC compresor clutch does not engage	Sign In

hello guys. I am new in this forum and i dont really know how things work. I recently bought a Fiat Grande Punto 2007 and i realised that AC was blowing only hot air. My first thought was that it needs rechange, so I did. After the recharge it still didnt work and the guy there told me that it may be a compresor problem and no power was going into the compresor. We changed the relay but as soon as i turned on the car the relay burned out, this happend 2-3 times. and also i hear a ticking sound , it maybe an eletrical discharge or something. So can any of you tell me what may be the problem?
thank you

Sounds like you need a better mechanic. He should have easily found the problem before going through 3 relays.

Which part of the relay is burning up? Relays usually don't do that unless the circuit isn't protected by a fuse and you have a short to ground after the relay. Even then the wiring may burn up before the relay is some cases.

You should have another mechanic check it out.
