Hi,

I have 2 issues which may or may not be related. About a month ago, I started my 2003 SS (just hit 100k) and the information center didn't come on. Then, when I turned on the blower fan for the heat, it didn't work either. After about 5 minutes, the information center came on, but the blower still wasn't working. After about 10 more minutes, the blower finally started working.

This has happened numerous times since then. I've replaced the blower motor resistor pack (the lowest fan speed never worked anyway...now this is fixed), and I just replaced the blower control unit with one from a scrap yard (the lights work on this one!). I suspect a short/loose wiring, but I don't even know where to look. Any help would be appreciated.

Thanks,
Jim

 

well if you have replaced them then u know what connectors to start with...get urself a manual and follow it from there

 

I wouldn't necessarily trust the one from the wrecking yard. Those modules are sensitive. Just my opinion.

 

I was hoping that someone else may have had this problem and could post how they fixed it. I dont' really believe that this problem is unique to my car.

 

i was gonna say sounds like a blower motor resistor
i always recomend never to get anything from the wreckers, always buy aftermarket from an auto parts store, its not usually that much more

 

I thought by blower he meant supercharger. Thinking how the heck does your supercharger work intermittently?

Back to topic: Are you referring to the information center by the rear view mirror that comes on after 5 min? I can't think of any other information centers but I want to make sure we are talking about the same thing.

 

Yes, that's what I'm referring to. Any ideas?

I did come acrossed a thread where someone had a similar problem and suggested the ignition switch connections might need cleaning/retightening. I might try that this weekend.

 

hey man im kinda having the same problem, with my 03 ss. where i go and put my key in the ignition, and i turn it to on or i start it which ever. but then i see on my dash that the cruse light is on (when it shouldn't be), and the message thing on the roof dont come on, and my heater dont work. then after a min or 2 goes by and it will all start working again. but if i hit the top of the dash, it works right away. so im just wondering if you, or anyone know/had this happen to them so i know which way to go with this. thanks for any help.

 

Back around March or so, I took the switch out and cleaned the connections with some contact cleaner. Everything's been working fine ever since. Good luck.
