Ok, so today i went to drive my car and the heat does not work. I press the button and the lights change and stuff, but no air is blown out of the vents at all! What possible things should I check to figure out what is wrong so I can fix it ASAP, it's *****ing cold here in Wisconsin! Thanks!

Have you tried different air flow "positions" (i.e. front, feet, etc.). Also, does the windshield defogger work? Have you tried to turn on the A/C? I am no mechanic, but if no air is coming out of the vents at all, it could be the A/C blower motor malfunctioning.

mcnelson

I tried the different positions, nothing happened. Front defogger doesn't work, a/c doesn't work. I am just guessing, but the a/c blower doesn't control the heat too, does it? Maybe I blew a mjor fuse, is there one that would control all of this? Like I said all the lights on the controls work, but nothing comes out of the vents.

The blower motor may not control the heat, but it does move the air, be it hot or cold. I don't know the innards of the system, but I will attach a snapshot of the manual page for a 93 GS which shows the A/C components. Generally, if there are problems with the airflow (or lack thereof), 1st place to look is the blower motor. If you feel comfortable, I can include a few pages on how to generate and read A/C error codes. Hope this helps.

If you can tell me how to genrate and read the codes that woudl be great. Is it that hard to do? Will that be able to tell me if it is the blower motor that is shot all of a sudden? I really appreciate your time and help. I can't wait to have some heat again!

I am guessing the 1st fuse to inspect is #28.

I will upload the error codes in the next 5 mins.


P.S. Fuses 1-10 are located in the "Driver Sidekick Panel" and the rest are in the engine bay fuse box.

I didn't know that our cars had an air filter for the air conditioning. Is this easy to change? What does "D-Opt" mean? Is it a dealer option? If it is, could we purchase the filter and intall it ourselves?

mcnelson

All fuses seem to be fine... I did the error codes and it displayed, 21, 23, and 42. I am trying to decide what exactly that means and what my next step shoudl be.

mcnelson

I tried checking what I could, and everything seemed fine. Now it only shows error 21 and 41. I ran the other check program and you can hear the different motors to kick in when it changes which face or feet, etc it is going to. So no matter what I do, no heat is blown out. How do you check relays?? How can I test the blower motor, could that be it?
