i just wanted to know what size bulbs are in a 2003 hvac panel and what you guys do to change them or how to wire in l.e.d

Two #74 bulbs, just like every other 3rd gen J-Body HVAC. To change them, you... change the bulb.

To wire in an LED, check out the interior FAQ. I couldn't have made a more in-depth write-up on wiring LEDs. Many others have followed the instructions to a T and have had no problems.

Don't know on the instrument panel (I assume you mean gauge cluster). And I wouldn't suggest tearing it apart to find out, either.

the gauge cluster is not ment to have its bulbs taken out..... they are"throw away parts" meaning if the bulbs blow you throw it in the trash and drop some hard earned cash and buy a new one. 00- and up.. you can swap clusters like no tomorrow. in my 01 i have a 02 sunfire cluster.... since their clusters come with red bulbs stock.

It's not normal for me to say this but...

This topic has been done to death lately.

A quick Search would yield a ton of info on this.
