Has anyone ever heard of an AC expansion valve
Just checking to see if anyone has heard of an AC expansion valve. i took my car to the shop the other day to get the AC recharged and the mechanic told me my AC expansion valve was not opening all the way and needed to be replaced. Im wondering where this part is located where can i buy it and has anyone else put one on their car?

my AC gets cool at highway speeds and in cooler weather around 70-85 but in stop and go and 90 degree plus weather it blows rather warm.

they call them TXV's, thermal expansion valve. if yours isnt working properly your AC will probably suck. replacing it should be left to a mechanic.
as for price? prepare to pay out the nose...

it its a lot of money but ac is not an easy thing to work on... especially if u have problems with the system leaking..... first of all the system is under pressure.. to fill it is a lot harder than one thinks.. the old stuff must be taken out under vaccum and filled and tested for leaks.. not a easy job at all

short of evacuating old refrigerant, nothing about ac work needs a shop. i know because i've DONE everything else. it's a lot of work, but it's easy because you can't screw it up. the worst that can happen is just that your ac doesn't work... provided you don't do something REALLY stupid.

Expansion valve replacement
1. drain r134
2. unscrew tubing nuts when tubing enters firewall (under the hood)
3. remove glove box
4. remove support bar behind glove box
5. You may have to cut or break the plastic trim behind the support.
6. unscrew and remove big black box
7. expansion valve is inside big black box. I didn't open the box but instead removed the valve throught the opening in the side. It can be challenging to get the tools in there.
8. Carefully install the new expansion valve. Do not kink the tubing!
9. put everything back together.
