So I've been having an ongoing issue with the A/C consistently blowing warm in my 2007 Civic. Took it to a mechanic last year who replaced the compressor at considerable expense - didn't fix the problem. After consulting another mechanic, I was advised that the TX valve or H block was failing and needed to be replaced - only problem is, they couldn't source a replacement, and told me to go to the dealership.
I'm concerned about inflated pricing from the dealership - which is why I've tried looking online, but to no avail. If anyone happens to have any ideas on where I could find a TX valve outside of a dealership I'd be very grateful.
