That's what I'm here for! Glad it helped you.

lol yeah it's quite a big project. I decided to fix my headliner while all the interior was out thats the only way to get a crew cab headliner out unless you take the rear window out.

I had to go to oreillys and find the right bolts, those bolts wouldn't come out of my OEM evap core. Any autoparts store should carry these type of HVAC bolts, it comes with a nut and has that E (backwards torx) drive head on it.

Try removing the fan itself, this is fairly easy to do and could be an area where these critters made their nest. to get the HVAC "module" out you have to take the dash apart and disconnect the bolts from the firewall side, it's not an easy job. I have the LT trim so to get the dash out I had to remove seats and center console. Despite what some of the comments say on this video I don't see how else you can remove the HVAC module without a dash removal. Once the HVAC module is removed you can separate it and clean all the valleyways that air is supposed to move through. I would reccomend getting brand new blend door actuators, AC Evaporator and a heater core just because these trucks are so old there's a decent chance these will go soon and you don't really want to have to touch this again.

Did you get it out? Was there a nest in the system?

The hack is also time consuming but considerably less so. You basically take a grinder, dremel, sawzall, to the metal bar behind the glove box and into the HVAC module to remove the AC evaporator. only problem with this is you need to place the plastic you cut off back onto the HVAC unit and then mud/plaster and reseal it so the air will flow through HVAC the module again. kzfaq.info/get/bejne/fdqZeKdn1sfShJc.html

Best way to do it right there removing the dash is for someone too dumb

No.

It’s easier to cut the box and do it

Still have the HVac box that’s seems stuck I took off all the bolts and ac etc off on the engine bay side and it’s still stuck to the frame

@@xSpoOky_AmBuSh Try giving it a good yank inside and see where it might be stuck at, see if you can feel tension somewhere on the HVAC box itself and perhaps you'll find your issue. I had to give mine a really good yank to get it off. Double check and make sure all the firewall nuts are off, there are some neaky ones right behind the engine and under the insulation as well. Here is a link to a wiring diagram www.justanswer.com/chevy/3fd86-2001-chevy-1500-4x4-a-c-5-3l-pickup-heater-core-leaks.html

@@djentlemanjoe5198 thanks so much it worked who knew how hard it can be lol 😂 been taking off nuts and bolts just to find out they had nothing to do with the HVac box lol 😂 Now I’m putting it all back together

My bezel didn't have a name on it. No BARB :( GOBBLESS

I would still do it this way, it was well worth the experience. Because this isn't my daily driver I had all the time I needed to do this project, if I was still daily driving this I'd heavily consider the hack for sure.

@@djentlemanjoe5198 yea...looks like you were at it for awhile. You went from socks and a tee to boots and hooded jacket. I appreciate the determination but i think the 'hack job' may be the better route. I've seen good hacks and bad ones. A lot of depends on who's doing it and how well they want to do it. Thanks for the vid.

should be!

HVAC Module box, verbiage seems to be different depending one what manual you are reading.

@@djentlemanjoe5198 ok

I have. 99 tahoe I think I need to replace the same unit. My air flow is weak. And only blows on defrost

@@michealrobinson9778 your actuators are probably stuck closed in the defrost only selection. You CAN recalibrate the system if you have the LT trim package with the digital HVAC control unit, but given the age this is probably wishful thinking. There are videos how to do that out here on youtube. You can replace some of the blend door actuator motors on the HVAC module without removing all of the dashboard

@@djentlemanjoe5198 yeah I’m going to replace the blend door actuator . How can I recalibrate the actuator before replacing it? I heard I can take the negative cable off the battery. And it will recalibrate. Will it!??

I've got a 2000 Silverado that I will be replacing the evap coil in soon. Think you could post a video of this process?

Double thumbs please. Need to see this method.

9:30 pm on a tuesday when the entire interior was gutted and I realized I needed to unbolt things in the engine bay to get the HVAC module out.

Hey Ray, on an LT package to get the crash bar out you need to remove the seats so you can get the center console out to remove the lower dashboard pieces. removing the steering wheel takes 2 seconds, it really didn't inconvenience me at all. Thanks for the feedback.
