Default Omron relay for 99 Vette

Is the Omron relay only available at the dealerships?

My ac stopped blowing. I checked the fuses and had a blown fuse #27
(10amp) in the inside fuse box. I checked the other ac fuse and it is fine. The only other thought was replacing the omron relay in the fuse box under the hood. Is there a way to check this Omron relay #12088567 or do I have to go to the dealer? Any advice is appreciated.

P.S. The ac will blow through the vents when I am driving and stops blowing when I come to a stop. Does that narrow my problem to any particular relay?

Manual or auto a/c?

Default Relay works- just read another post on testing the relay

I may have answered my own question. I just removed a good Omron relay switch from another circuite(horn) which is the exact same part #, placed it in the a/c relay slot and still have no ac. I placed the relay I thought was bad in the horn slot and the horn worked.

So I guess I still need to find my ac problem.

Suggestions anyone?

PM me your email, and I can send schematics.
