2005 Silverado Recall Letter From Gm

mikewood31 · April 28, 2011

Anybody get this recall letter in the mail on their 2005 silvy

from GM regarding the blower motor resistor relay module & connector?

Does it cover only 2005 models? Mine is a 2006, but made late in 2005.

And what is the problem? Overheating? Loss of function?

mikewood31 · April 28, 2011

the letter says it involves certain 2005 model year silverados

equipped with manual/AC or heater only systems

"the vehicle may have a condition where the interface between the electrical terminals

of the blower motor relay resistor module and the associated wiring connector

may be incapable of conducting higher current levels for sustained periods of blower motor operation.In addition,moisture and other contaminants such as road de-icing materials may enter the fresh air intake plenum and contact the internal circuit of the module or corrode the terminals.Either of the above may cause the blower motor relay resistor module or wiring connector to overheat resulting in one or more of the following symptoms: The Blower motor may not function at all speed settings

A burning plastic smell or smoke may be present in the vehicle

The HVAC blower may run continuously after the vehicle is turned off"

"They recomend not idling the truck for extended periods with the blower running on high

or leaving it running unattended

they are working with there suppliers to obtain the parts to correct this condition

as quickly as possible ,when parts become available they will advise with a second letter

and that they have taken this action in the interest of safety and continued satisfaction

with there products"

I can say we just went through one of the longest coldest winters I can remember

in Canada and my heater motor ran alot and I have had no problem so this may be

just a precaution, but I wanted to know if any of the guys in the US have had this done already or heard about it

interesting...brownie points to GM for issueing possible help for 6 year olds trucks but it raises the question of why is it it only 2005 trucks? what about 2003s,2004s and 2006s?

I got the same letter yesterday for a 2006. I suspect it covers more than just the 05-06 model year and we were the lucky ones to get the first letters.

Hmmmm....I wonder if this would cover my 2006 with a blower that doesn't work on speed 1

i haven't got a letter

Every single gmt-800 at my work has had one of those melt! Or completely stop working. Some of them we actually bypassed everything and just put an on/off toggle switch in a pinch!

Again this is for those with the MANUAL climate control system not the auto system.

Thanks for all the Replies Guys

I always check here first for a reason when it comes to my trucks

and I agree I think its great that they give us the heads up even 6 years later

maybe its only the trucks built for Canada . Mine was built at the Michigan plant

according to my vin but I am going to talk to my local dealer and see what he knows or will tell me

I will post what I find out

update

look what I found on the transport Canada website

lists models from 2003 -2007 to be fixed by the dealer

My dad got this letter yesterday for his '05 Sierra.

I have manual A/C controls - no letter yet.

I got the letter, for the 2004 model year. I actually had to replace the resistor module a few years ago as it was "not blowing on all speeds", as they mention in the recall letter.
