My temp gauge climbs when I turn on A/C. It never rises when idling or driving only when I turn A/C on. It blows cold.

Question type: General

works fine it just concerns me. It might be normal to climb but don't want to take
that chance.

How much does the temp go up? The AC does put additional heat load on the cooling system. Make sure your cooling fan is working properly.
