I HAVE JUST GOTTEN MY A/C SYSTEM REDONE AFTER AN AUTODESTRUCT OF THE COMPRESSOR,(LIKE BUYING ANOTHER CAR). IT OPERATED OK ON THE WAY HOME BUT THE NEXT MORNING IT WOULDN,T COOL AT ALL. LOOKED AT THE SYSTEM AND COULD SEE FREON (12) IN THE SIGHT GLASS. CALLED THE MECHANIC AND HE SAID TO RETURN. NEXT MORNING THE A/C STARTED AND OPERATED BETTER THAN EVER ON THE WAY TO THE MECHANIC. AS I WAS LEAVING HIS PLACE IT WOULDN,T START ONCE AGAIN. HE PLAYED WITH THE BUTTONS AND SAID THAT IT WAS THE CLIMATE CONTROL UNIT. I REMOVED THE UNIT , PART # 126 830 08 85 AND LOOKED FOR A REPLACEMENT. FOUND A 126 830 05 85 AND INSTALLED IT. NO COOLING AT ALL. IS THIS A SUBSTITUTE? OR DO I NEED AN EXACT # OR IS THIS ANOTHER BAD UNIT? ANY SUGGESTIONS? OTHER CAUSES OR PROBLEMS

 

yes it is a replacement of the previous one and can use.

maybe your problem is not from there.
