We have a 2003 Sonata that needs to have the heater core replaced.
The temp. is getting hot out here in the desert (AZ) and we'd like to
get this replaced so we have A/C, but our money is really tight, so
can't afford to have it done by either the dealer or a repair shop.
So, I'm thinking about doing it myself, but cannot find any
information about how to do it. Is there any online source/manual
that will give me step-by-step directions on how to do this?

We have metric tools and fair mechanical ability, but at my age (64)
and size, my physical dexterity is somewhat limited.

Thanks for any suggestions any of you can provide.

Unfortunately, you'll need to remove the dash. You can find repair manual
at www.hmaservice.com. If you don't already have a free account there
you'll need to register.

I'm a little confused about why you need to replace the heater core t
have a/c. The a/c should work regardless of whether you have
functioning heater core
 
Thanks for your response! I gave your message to my son, who in turn
discussed a solution with his service provider. They agreed the
problem was the leaking heater core and it had nothing to do with the
coolant smell he got anytime he tried to run the A/C. So, yeaterday
they changed the hoses going to the heater core to bypass it, and that
solved his problem.
So now he's happy since it's starting to warm-up out here in the
western desert.

I sure hope he plans on finding a new mechanic and getting that heater fixed
before he needs it this fall. Talk about a cobbed up fix...

I'd avoid that mechanic like the plague in the future.

As a teenager, I did that to a couple of cars to get by for a while. I even
drove my '61 Bonneville for a week with cardboard blocking the hole in the
firewall until I got the heater core fixed and back in. That was a very
cold week.
