I am replacing my expansion valve. Ive read numerous time it should be done along with compressor and accumulator.

I have the glove box off and see what I think is all the bolt to get the box out. Only problem is there is one located up up the airbag close to the a pillar. I believe there are 7 all together. Then the 1000 screws to separate the to halves of the box.

My questions are.. Is it necessary to remove the box to change the expansion valve? Is their any other hidden bolts? Is there a diy by chance?

 

Quick question, what problems are you experiencing with your AC? Sometimes mine doesnt cool right and even on 60 it takes forever to get cold. My vent thermometer says 60 until I get up to speed and the rpms start moving high. Just wondering what your symptoms were?

 

^^ Stop. You do not need to take the blower unit out. The evaporator unit will come off by itself leaving the blower unit in place.

The expansion valve is on the back side of the evaporator unit.

You do not need to change the receiver/dryer if you remove and replace the E valve right away. Long as you don't leave it open overnight. The replacement dryer will need a 1/3 fl-oz of replacement ac oil.

 

01acls Thank you. I found that out yesterday. It was the first time I was able to say the words "well that was easy" while working on a car. I am glad I got in there, the amount of dirt and pine needles was terrible. Its squeaky clean now and my car should smell wonderfull when done. I have only done setups that required the dash to be pulled off. And the box contained evap, heater core, blower motor and expansion valve. Big thanks to acura for making it easy.


ndoghuntsville at first there was a leak - found leak and repaired it. I had ice cold air but the compressor was making the same sound your power steering pump make when it has air in it. I ignored the sound and I am replacing now because it start to make the common noises of fried bearings. As well as when I would turn the a/c on it would bog my car down almost to a stall when the clutch engaged. I think the field coil was the main culprit. I never tested to see if it was bad. But the puff of smoke that come off of the compressor and burnt electrical smell I was getting suggests it fried.
