I am replacing the blower box assembly (because the fan blows so weakly) and Helm's manual shows disconnecting evaporator lines. Doesn't this mean I will need to redo the refrigerant?

Anyone done this? Tips? Advice?

Charles,
If you replace just the blower motor I have heard of a way to wiggle the motor out without evacuating the A/C system.
If you are going to replace the whole blower box asy you will have to have the system evacuated.
GL on the repair.

BTW:If you decide to evac the A/C please...please...please do it properly.Dont vent the freon into the atmosphere.

By the book,You would have to discharge the system.. :cry:

There are however, a couple of ways to cheat...

What I did was to make a single, straight horizontial
cut in the black insulation against the firewall
and peel it back out of the way.. Mine was already ripped..

The added clearance gives you almost enough room to wrestle it out.
Loosening the blower box and surrounding dash so everything has some give will also help..
I coated everything with WD-40 to give it less resistance on the way out.
It was not easy,but it is possible..Take care not to break the
plastic blower wheel.

Another method I have heard of,
You cut a small hole in the filter screen,or peel it out of the way so you can get a
1/4" drive socket in and remove the nut that fastens the blower wheel..
You then remove the motor followed by the fan blade..

When I replaced mine,I made the mistake? of getting it from the dealer.
It was very expensive and it really doesn't seem to blow that hard..
An aftermarket unit would probably be as good or better..

While you are inside the dash,Inspect the evaporator..
Mine was full of dog hair from the previous owners pet.
I used a commercial-type foaming evaporator cleaner
to remove as much as I could without removing it or discharging..

I will try to find the article on getting just the motor out to test it.

Not sure if I give a damn enough to go to the shop and have the R134a evacuated.

Good info. I will probably be working on this with it hovering around 100F here. My wife thinks I should wait until fall when it is cooler and just tough it out for now. (I invariably screw things up on my car and have to redo several times over a period of weeks).

Problem is, I may have a real job in the next week or so and can no longer just sweat it out in shorts and a T-shirt.

If I had it to do over again,I would probably
use an aftermarket replacement motor..

The 1995 Civic I have has one of these and
it blows a heck of alot harder than the OEM unit
in the CRX that cost me around 200 bucks.. :rolleyes1:

All it says is: UNIMOTOR 14634 03146 made in Canada..
{Number for a CRX may be different}

>>>>EDIT: I believe this may be the manufactor:

Just make sure you test the new motor to see if it's the kind of motor that you want. I bought an aftermarket one, and it ended up being REALLY noisy all the time. There are different types of electric motors. Usually the ones with carbon brushes are quieter, but eventually wear out.
