'93 Miata heater control - repair or replace

Hi all.

Last fall I posted that my heater/air flow/vent controls were not
working correctly.  Well, I took the console apart today and took out
the heater control.  I found that a cable guide for the air flow (?)
(vent/defrost/etc) control was broken off.

Picture of heater control with broken piece where it should be.  The
broken piece is the cable guide at the center of the picture for the
cable going off to the right:

Picture with broken piece removed:
http://www.buckeyemiataclub.com/jah/clamp_removed.jpg

Picture of broken off clamp:
http://www.buckeyemiataclub.com/jah/clamp_removed.jpg

So, my options seem to be to either replace the heater control or
attempt to repair it.  If this was easier to get to, I'd consider trying
super glue.  I don't know if that is a reasonable thing to do for this
piece.  

Useful suggestions welcomed :-)

Jim

Replace only, do NOT attempt repair for reasons you state above, it's
too hard to do it over if the repair fails.  

Check Ebay, junk yards, etc.

Sounds good.  You can post here or the reply to address in my posts
works.

Does anyone happen to know if the heater/air conditioner control box
from a 1996 model will fit a 1993 model.

Jim, definitely check the sources that Chris listed.

The one that will probably work for you is from a 1991 model and it
needs to be removed, which could be next week with my schedule.
Since it is older than your's, it could easily develop the same problem,
though it could also work for years to come.

Have you priced a new one? (shudder)

I haven't.  I have a query in to Planet Miata but haven't heard
anything. Last time I checked with a dealer about parts, it was hit or
miss if they were available for a 93.

Same as any dealer part:
1. open trunk
2. stuff full of $20 bills
3. head to dealer, you may have enough if you packed the trunk tightly
enough.

I don't even know which of these is the part:

"Dash control unit, miata mx5, w/o detachable top"
or
"Dash control unit, miata mx5, w/detachable top"

Detachable top on the hvac controls?

Also, with this warning on the page, I'm not sure those are current
prices:

"Due to a pricing increase on July 1st 2006 some prices may be
incorrect."

I've sent a query to finishlineperformance.com.

The weather here is so nice, I'm tempted to try the superglue and
re-assemble everything.  At least I could drive the car until I get my
hands on a replacement part to install.

Thanks.  That's the conclusion I was coming to.  On with the search!

i can also vouch for pat as a excellent source for parts, and a all around
good guy, but you could also try contacting www.planetmiata.com for used
parts, or www.finishlineperformance.com for new.

Thanks Chris,
I will around tomorrow. I have one on a Miata that will work for Jim,
but getting it out might take me a few days.

I will look in the parts buckets tomorrow, need to clear that stuff out.

So, just to update this.  Just for fun, I tried the super glue, it
didn't work.  When I took the screw out of the broken off piece, the
plastic fell apart into small pieces.

This evening I installed a replacement that I obtained from Planet
Miata.  It cost $15 for the part and about $11 for shipping.  I called
them Tuesday morning and the part came today.

I also checked with www.finishlineperformance.com, a new replacement
would be $169.95, but is available.  They said it would take them a
couple of days to get it.

Thanks for all the input.

You got a great price, and from personal experience, the shipping was
very reasonable too. (light weight part, awkward shape with the cables)

Please let us know if the part is in good shape, so far I have only
heard good things about planetmiata.com.

It appeared to be in good shape.  Everything worked the way it should.
It is installed now and I just replaced the original door speakers.  Now
if only the weather would cooperate.

Replacement wae the best option--
Repair is possible by securing the cable jacket to the control frame with
almost anything that will hold it in place.
One concern is that the cable or the flap operated by the cable may be
binding. If so this will shorten the life of the replacement control unit.
A problem is the usual brittle plastic issue that occurs with old plastic
parts. Seems the control unit suffers from it.
(As well as the console surround and the instrument cluster hood .) We used
to figure that ten years was about when the plastic got to the point that it
would break easily.
