Hey guys this is a continuation from the topic engine drop but we are now in the electrical phase which of course is complete hell.
To recap on this situation I am getting a cooling fan 1 code with fan staying on after car is off and killing the battery and I’m getting open circuit for 02 sensor B3 S2 and B4 S2. Sometimes I notice one of the 02 sensors sometimes will work or will show slow response. When it’s working the car will barely shake to where you really won’t notice it but when that one isn’t working the car will have a shake that is a bit notice because you know both of them aren’t working.
Before then when I first got the car it would randomly cut off on me and would do either a esp fault or a brake fault which has been happening since last summer when I got the car. I recently discovered by me getting very frustrated when the car was cutting off crazy and leaving me stranded and when the car cooled down it would run for some time and do same thing and also the relay was so hot it burned my hand when I checked them.
After that I started checking all the relays by changing them but then I got to relays that was in the driver’s compartment and first thing I see is the steering rack piece is rusted I’m not sure if it’s supposed to be like that but it’s been like that for a long time obviously. I assume this was probably from where car got flooded on the vehicle history. Of course changing them worked.
So now here we are with 02 and cooling fan 1 code and almost forgot I have got a code with something for thermostat that’s electrical but the car doesn’t overheat. So recently since that cooling fan 1 code the relay started burning out for the engine computer with now showing that thermostat code is latest one that appeared.
The relay that is burning out is 7.1 and 7.2 they are a separate relay I believe they work off of each other which one is horn and one is the engine computer
