My qx 4 has been over heating for some tyme so I took it to a mech for a change of gasket on friday and I specifically told him to b careful wit d ac. I went to pick it up on monday cos I travelled for d wkend and discovered dat d ac was no longer cooling he told he did not touch d ac mayb it need gas. So I took it for a refill added 1 can of 134a bt there was no change at all in cooling I was advice to buy another compressor. So I took to another ac technician who happens to b my neigbour so he removed d dryer and flushed it refill wit 1 can still no change he then advice dat 1 shud buy another compressor. My question is dis. Is it possible for d ac compressor to go bad like dat witout any warning? Pls advice is urgently needed cus d weather is hot here in d north nw so I need d ac. Tanks.

The wires to the sensor may be damaged and will need to be repaired.

Boss I fail to belive the bolded.

A good A.C technician can test your compressor to find out if its working without wasting several cans of GAS. Have your compressor tested.

P.s what part of the north?

What sensor?

Colding sensor or hotting sensor?

Where's it located?
