I recently bought a 1978 280Z. The compressor runs but the AC doesn't cool. The system was just converted to R134 but the seller says it needs the expansion valve replaced. How hard of a job is that and does the dash have to come out. What should I expect to pay for this repair.

Do you guys thinks it could be the expansion valve or some thing else?

Thanks

Randy

The dash doesn't have to come out to change the expansion valve. It can be removed after removing the finisher, finisher brackets and center air ducts. A bad expansion valve could cause the system not to cool but so could several other things. If you are unsure that that is the problem the only thing I could suggest is the have it inspected by an AC shop.

What are the finisher and finisher brackets and where are they located?

Thanks
