Air-conditioner On One Side

[bpricetex]

Seems the air-conditioner only cools on the right side. There is a 20 degree difference between right and left vents. Anybody know what causes this?

expansion valve is faulty or malfunctioning.

It is a common problem with earlier ES's.....what year is yours?

Stevie how is the expansion valve connected to the left and right side controls?

Agreed ,,what year>?

So, what the heck is an expansion valve? The auto is a 1996 - great otherwise.

sk, I don't know exactly why it creates this symptom and how exactly it works, but every post that I have read that had faulty expansion valves has this as the major complaint.

sk, you could SEARCH on expansion valve and see what your take on it is. ( :P :D boy oh boy, have I been wanting to say that to you for a year now) just playing with ya buddy.

bpricetex, I don't know exactly what the valve does. I do know it is right up by the firewall and is a PITA to fix. Cost of fixing it varies but is in the neighborhood of $500.

There is another possibility. Does your 96 have dual climate control. Maybe the setting for one side is set hotter than the other side. If so, you would see a button that says DUAL and the light would be on. The passenger's side would have a separate temp control. My 02 has this, but I don't know what year it was introduced on the ES.
