My 03 Altima 2.5S AC compressor wont engage, I took it to an AC shop and he told me he checked the pressure and everything is ok... no leaks. the compressor is not getting any power as well as the radiator fans. I tryed buying a computer from a junked car, connected it and still no power. all controls and blowers work fine.... what is the problem???

He said he checked the relays and they where fine but what should I look for?
There is no info on which relay controls the ac on the manual or on the cover
is there a way to check if the relay is burend out? If so how? Do I remove and shake it? I. E. Clueless... He said he checked the relays and they where fine but what should I look for?

Here is where the AC relay is located for your vehicle: The A/C relay is in the IPDM (that black box next to the coolant tank).

I'd still like to know weather you have the Automatic or Manual a/c System

depending on which unit you have could depend on location of "switch/sensor" but I suspect it is the thermo-control amp behind the right side of the dash

regardless...it is you LEGAL right to ask the dealer to show you the location of the part they replaced and to provide you with the old part

when you get the old part take a picture so I can ID the part and teach you how to test it of later reference

I wish I would have checked my email sooner, I picked the car up yesterday, didn't get a chance to ask for the part or the location.... wanna hear something weird.... the trunk opening switch at on the door now doesn't work... I checked all the fuses, the switch next to the glove compartment is on.... do you think they disconnected something while working on the sensor? should I take it back?
