I am trying to get to the expansion valve on 1995 Camry. Removing glove box and blower motor is no problem. Problem is removing the blower motor housing to get to the access panel to the evaporator. How do I remove it?

 

Remove ECU and bracket.


Disconnect wiring plugs and wiring plug bracket.

Disconnect any wiring plugs from the blower unit.

If manual climate control disconnect air inlet damper cable.

Remove screws (3) from blower unit.

2 are facing the drivers side (in circular part of blower area), 1 facing firewall (above what must be the recirculate air intake duct).

 

Thanks for your reply. I may not have been specific enough though. I have the blower motor out. But the housing that contains the blower wheel has a molded bracket that attaches to the evaporator access panel. Therefore, the referenced housing must be removed to get the access panel off in order to change the expansion valve. However, maybe the last two lines of your reply actually addresses my questions. Just wanted to be sure. Thanks for advice.

 

Remove horizontal trim piece directly below glove box along with underside trim extending towards firewall. There is one screw located on the horizontal trim to the left, the rest of the trim is merely held by clips. The nuts attaching glove box will be exposed, remove them, the door will slide out. Remove three black screws on upper inside of glove box, pull out and remove small gray connector and large yellow one. Remove two black screws holding wiring harness to blower fan and additional white connector. Remove three brass screws holding blower motor to housing, it will drop down, and remove blower motor and wheel. Remove ECU (three gray connectors) after removing small black box which blocks access to lower bracket nuts and top two brass screws. Next is the blower motor housing. Remove: lower brass nut located at inside firewall:screw just above A/C lines coming thru firewall;screw towards front housing to access panel. Remove two duct pieces running lateral to upper glove box frame to get last screw. Disconnect blue cable. Lower entire assembly. Remove two nuts holding A/C lines to firewall. Slide out evaporator with A/C lines.

 

Thanks for posting back with your excellent detailed procedure on removing the expansion valve!

Glad you were able to get the task completed.

 

Sure. Hope it helps someone out in future. The only thing I forgot to mention is that, although the blower motor housing consists of two pieces, upper and lower, it is absolutely unnecessary to remove the lower from the upper. The entire housing can be removed and installed without separating the two pieces and, it is almost impossible to reinstall the lower housing to the upper if the upper is installed first.

 

I'm about to change the expansion valve but wanted to see if you were having the same problem. For a while, everything worked OK, some days cold some days warm air. Now, I just get warm air. I changed everything accept the expansion valve and core. I was just trying to get an idea of how long it took. It looks like a real bear to get out but those instructions look good. Any additional advice would be appreciated. Especially special tools.

 

You won't need any specialty tools. My biggest problem was not realizing that since the blower motor housing is in to pieces, upper and lower, you only need to remove the lower part. Otherwise, add on about 2 hours to the project. Since you're doing this for the first time, give yourself at least 4 hours.

 

Just wanted to say thanks to ( markmmv ) for instructions on getting to expansion valve.Any one wanting to do this markmmv is right one the money this is the way to go.
