#2 of 11 2004 Z71 Tahoe Horn going out
Apr 09, 2007 (11:35 am)
I have a '04 Z71 Tahoe. The horn is dying out and I wonder if there is a fuse I can replace or should I take it to the dealership.
#3 of 11 Heater fan runs but no air
Sep 11, 2007 (10:11 am)
97 GMC Suburban - the heater/ac fan runs on all different speed settings but after a while (1 hr or so) nearly all air stops coming out any place (not defrost, vent or floor). This happens in cold or hot weather with ac or heater. Sometimes if the cars is turned off and then back on the fan works but it gradually stops coming out on every trip longer than approx 1 hr.
Thanks in advance for any tips/help!
#4 of 11 heater core clogged?
Feb 02, 2008 (5:50 am)
I recently had intake manifold gasket problems and was told to add some "stop-leak" type of product. It didn't work and I eventually had to replace the engine with a new crate 350. That's when my problem started.
When the mechanic removed the engine, air got to the coolant in the heater hoses and turned the "stop-leak" to an oatmeal consistency. Now the heater core is clogged and no heat is the result.
My question is, can the heater hoses be taken loose and a pressure sprayer be used to blow the sludge out or will the core need to be replaced(It worked fine before the transplant)?
Any help would be appreciated greatly, It's cold.

There is a fuse for the horn, I am not sure which one exactly but my husband replaced the one in his 2001 truck and it took care of the problem
#6 of 11 Horn Problem/Location on '03 Chevy Venture

The horn on my wife's '03 Chevy Venture doesn't work. I checked the fuse, and it is fine. Where is the horn located? Are there two horns--in different locations? How do I determine what needs to be replaced?

I own a 2004 Suburban and I had three problems with my horn due to the contacts were not touching each other, so the dealer had to modify the contacts to touch each other..

I don't have electrical schematics for your year, but have a factory set for my 2007Sub. The horn circuit basically has three pieces:
- the horn switchs
- a Horn PCB relay
- a 15A Horn fuse
Check the fuse first, and then the relay, and if you have to get to the switches you have to get into your steering whell behind the airbag.

I cannot locate the horn on my van. It is inop but I have voltage through the relay. Does anyone know where it is so I can check voltage.
