hi friends
well my a/c stop working for a while,i have checked everything and its ok. if i use an external thermoswitch it works but the vsv doesnt,but if i connected again the a/c amplifier unit the comp wont engage,a friend of mine did some tests on the a/c system and all parts and functions seems to be ok except for the a/c amp.
so i grab the service manual and verify the a/c harness and all values are ok the only values that i didnt find was the ones for the a/c amplifier to make a test in the card.

any info about the a/c amplifier card values will be great
thanks in advance.
