GMC: I have a 2004 GMC Envoy. The ABS light and the brake light

Customer Question
I have a 2004 GMC...
I have a 2004 GMC Envoy. The ABS light and the brake light come on and at this time the heater blower motor stops working. This happens everytime I drive. I had it scanned and the codes are U1041, U1000, PO128. There was no live data coming from the vehicle while in motion from the speed sensors. Can you help me?

I encountered a very similar concern once and it turned out to be the ignition switch. A faulty ignition switch will cause strange problems such as this. They are also a very common issues on these vehicles. The ignition switch provides the power to the ABS system and the air conditioning system. If the switch shorts out the above symptoms are a possibility.
