The electrical system is similar on both units. Unfortunately you'll have to have a computer hooked up to see if they can find any codes causing th problem it may be just a bad ground or dirty ground causing the problem. It can still be one of the relays and going to the dealer the mechanic may know which one goes bad all the time. I know prices aren't cheap at the dealer and an intermittent problem like yours are not easily diagnosed. On the left side of enginge compartment there are 7 fuses you can check, they will be marked and see if they are bad. You will ve able to tell when you pull them out. There is also a climate control relay there which should be marked, you can pull that out and put it back in as they sometimes get dirty. The inside cover should have which fuse is which as well as which relay is which. That is something you can do if you don't mind getting your hands dirty. They may pull otu hard however.
