2004 JGC needs new "H-valve" ??
A few questions.....
Noticed the ac not pumping out cold air. Took it in, and they said the
h-valve needed replacing.
Just curious if this is a common issue with the grand cherokees?
Also, noticed after picking it up from the dealer, whenever the ac (or
defrost) is on, I notice a slight clicking noise that coincides directly
with engine speed. (put in Neutral, sit idle, slow click, give it a little
gas and click picks up) As soon as I turn off the ac or the defrost, the
click goes away.
The part needed was not in stock, so it's on order, I'm hoping this will go
away when they replace the defective part?? Anyone have a clue what's
happening here?

My question is what is an "h-valve" or where does it go.

Both AC and defrost run the compressor. That click is the compressor kicking in.
Your Jeeps computer also speeds up the engine a few hundred RPM every time the
AC compressor starts. Perfecly normal.

My initial thought is someone's blowing smoke up your backside.
But since it's an 04 and should be a warrantee issue, let them
fix what ever they need to fix.

I can't think of a valve in an air conditioning system, they might
be talking about the high pressure switch:

Compressors make noise, your sound may be normal, anyway bring it up
when you go in to finish the service.

The only valve in a ac system I know of is a "Expansion Valve". It's right by
the firewall on my 96 xj and both ac lines fo through it.
