Diagnosing this will be subject to a process of elimination. It could be the radio, blower motor or any other accessory particularly ones with moving parts; Try switching those off and try to note when this problem occurs and what is on/whatyou are doing. Something is getting hot causing the smell so it will be a situation where the accessory will have to run a while before doing it. It is a possibility that there is an electical curcuit overheating, but less likely. Lets rule out accessories first and give us an update. GL

Hi I own a 2003 Cadillac CTS I am getting a check engine light error light with code P0128 and my heat is fluxuating up and down I have already installed a themostat. What are my options

A code P0128 may mean that one or more of the following has happened:

1-Low engine coolant level
2-Leaking or stuck open thermostat
3-Faulty cooling fan (running too much)
4-Faulty coolant temperature (ECT) sensor
5-Faulty intake air temperature (IAT) sensor

Check coolant level
Check to make sure thermostat is functioning properly Check the Cooling fan Check the ECT sensor Check the IAT sensor If all else fails replace the thermostat
