#146 of 5688 2500 heater problem
Feb 09, 2001 (9:09 pm)
My 2000 2500 LT doesn't put enough heated air into the passenger's footwell. An end of year trip from Colorado to Tennessee had whoever wasn't driving setting there with a blanket wrapped around their feet to keep them warm. Outside temps. were 12 degrees and the driver was hot (baking actually) so the heater was putting out but not much was going into the right-side footwell.
Is anyone else having any similar problems?
My dealer and Chevy's Tech Support claim the heater is working to spec. but Customer Assistance noted that Chevy has a "Poor Heater Performance Review" for Silverados already going.
Any help would be appreciated.
#148 of 5688 Horn pitch

Is there a way to change the pitch of the horn in a 2001 Silverado 1500? If there is, then I have another question: exactly where is the horn?

#150 of 5688 change the pitch
Feb 12, 2001 (4:09 am)
...yeah..with a hammer!
..Horn should be near front or side of engine compartment
#152 of 5688 not a hammer

don't use a hammer for adjusting horn pitch. actually tim, there is an adjustment screw that is held in a locked position by a locknut. it determines how much the horn diaphram moves which in turn allows a weaker or stonger volume from the horn.

I think Tim was making a joke! Lighten up.

The adjustment screw is not for volume, it is to adjust the pitch of the horn. Each horn is designed and manufactured to work at a specific frequency. The adjustment screw is used to set the horn to that frequency.

I agree with Mike L's analysis. I'd personally go back to a stock filter.
The other thing I'd do, is pull all the plugs after some light highway driving and check mixture. If plugs are reading good, then you pretty much are getting about what you should.
BTW, I'm a leadfoot, drive a 4.8L manual 4x4 4.10, and get 16mpg most of the time empty, towing down to a low of 7mpg, and running 82mph on the interstate with the bed loaded with camping gear and a dirtbike, round trip 400 miles I got a little below 15mpg. I have a 2500HD CC 4x4 5speed on order, and expect to get about what you get for mileage. And if we had the 8.1 we'd probably get 15 to 20% less mileage....
