2000 Chevy Silverado Ext Cab---Cold passenger feet

19 posts in this topic

I have owned this truck for about 60,000 miles and every winter my girlfriend complains her feet get cold when I have the heater control set to fresh air. I let her drive last winter and I noticed the same problem. My solution has been to turn the control to recirculated air for a few mintutes, but then I have to turn it back to defrost my windshield. Is there a reason I'm getting such a draft from the cold air intake? What's the solution?

You may have to replace the cabin filter behind the glove box. I did mine last summer and had leaves and every thing else in there. $14 for the filter I tinnk. I have a 2000 silverado ex cab

GM had a bulletin regarding this several years ago. There can be an air leak from the cowl into the heater box. You need to remove the trim on the cowl by the wipers. Under that you find a oval shaped metal plate that is sealed with caulk on the pass side. You need to scrape the caulk off and with a chisel break the plate loose and remove it. Inside of that is a passageway that supplies air to the heater. The seam inside that passage is leaking and allowing cold air to come in behind the glovebox. Seal the seam up with caulk, or sealant. I have used the sticky alum foil tape. It's a little easier to work with. Doesn't have to be pretty. Replace the cover and hold it down with a couple sheet metal screws and recaulk around the edge.

That's exactly what it feels like! I figured there had to be a direct leak to the outside somewhere. I'll check it out, thanks!

Glad to help out. I've done a couple of mine. Pretty common problem. Takes about an hour and really makes a difference.

hafnutz could you tell if the seam was leaking or did you just cover the whole seam?

I just posted a question about the doors on my 98, but wondering is this is the same thing you guys are talking about. Do you know if this might be affecting the old style 98 ext cab, or is it just the newer body style? Thanks.

The last one I did was my 99 Suburban but if I remember the bulletin was for the newer bodystyle (99 and newer pickups,2000 and up Sub and Tahoe) Sure took care of my problems. The seam runs all the way around the plenum. You cannot see most of it you can only feel it. You have to open the plenum up to get to it. It's not really a big job at all. Just go in and smear some silicon or seam sealer or even tape it. As long as it sticks. If you feel cold air coming out below the glovebox this is most likely the problem.

Maybe we should gather on a lake somewhere and set up an assembly line to fix all these while wetting a couple lines??? LOL

I'm in for it. Next time I'm at my dad's shop, I'm going to have to take care of this. Others had told me I had a fan that was out. Thanks!

Well, I had an easy solution to my draft. Little did I know, I have cab filters between the fan and the heater core. After removing the large cover over the heater core assembly, I found a "trap door" and inside there is two small filters side by side. PLUGGED SOLID. Everyone's happy again...and warm!

Thanks for the input! cool

How do you remove the trim on the cowl by the wipers? Is there screws or does it just snap off?

I took on this project yesterday afternoon, I dont really see what I am supose to be sealing. Where do they leak? Is it the joint that is sealed with foam? I taped up that joint and put it back together.

There is a seam between the airbox inside the cab and the firewall. You cannot see some of it but you can feel it. Sounds to me like you got it. It's been awhile since I've done one. Don't remember if it has foam tape or not. My guess is probably.

Funny??? I asked this same question (except it was for the drivers side) and got 1 reply on the subject over the last couple weeks.

Is this also the case with my 96 too then?

    • Hey you guys-you forget I'm an old Alaskan.  I know all I need to know about the dingbat and her famous family. If you are actually accepting her blather as useful intelligence and knowledge than you are as squirrely as she is. Let her just fade away for Pete's sake.
    • Hi Dave.  We have talked about this briefly a year or two ago.  Due to the paranoia factor on this site I and most others aren't here as much.  I do miss guys like you Dave.  I remember the pic of your camper at Itasca so we took a drive through this summer.   I wondered where your spot was.  Man I hope you come out of this alright Dave.  My Uncle had diabetes bad and finally lost the battle.  The docs said change your diet or take the shot.  He said give me the shots.  Well that lasted for many years and his body finally gave in..  He should have changed his diet too.  I took him to a couple of bear baits he wanted to see and he told me his feet were finally giving in.  AND he was a tough guy.   Anyway Dave we all love you and I hope you can persevere....   I am thinking good things for you so you think positive too.....    Barry.    Hope this isn't deleted for one of their paranoid reasons...  If it is deleted I will never be back as many others.   So sad.....
    • It is interesting how people got out so early.  I have done it too.  3 or 4 hits with the spud and it is alright.......  NO it isn't ....  It is manly to talk about getting on the ice first.  Well now that I am older I realize it is stupid talk not manly.  The fishing sales world is just as guilty.  They talk about the first ice fishing being so good.  They actually are hugely responsible for getting stupid people out on thin ice.  The lets make a buck is more important than anything.  ANYTHING!!! 
    • Great pictures.   I'm used to seeing eagles, but those pictures are outstanding. 
    • Didn't I just do that?   Can't you read? 
    • Only if they have a drinking problem and maybe me implants.  That's all the Canadian folks care about....
    • That sounds like a great idea. 
    • I know perfectly well how phishing works.   Typical Liberal thinks anyone who is not toeing the party line is ignorant.    It isn't that hard to phish a fool like podesta.
    • I feel like we were just water skiing not to long ago!  Definitely caught a sun burn for deer season ha.  I'll be doing my fishing at the grocery store for a bit yet.
    • Remember, your fishing for pickerel!!  No such thing as walleye where your fishing
