Flashing cruse control light?

SOURCE: Check engine light came on

I did end up taking my car to the dealership where I bought it. They were great! He knew immediately what the problem was. Of course, they still did a thorough check too.
Anyway, it turned out that the plug to the electronic system had been knocked loose. This caused the check engine light to come on & the cruise control to not work (you were right, if the check engine light is on, cruise doesn't work). As for the door, that was simply the switch plate needing to be adjusted.

I had this occur on my 2007 Subaru Tribeca. ABS, Traction Control, Check Engine lights were solid, Cruise Control light was blinking and "Er SS" (commonly misread as Er 55) displayed on Trip Odometer. All lights were cleared after 10 or so miles. It appears this is a Speed Sensor (SS) reading error whereby the computer notices an irregularity with the readings taken from the four wheels. Most often it is a temporary and harmless glitch and sometimes a result of debris that is impeding the sensor's reading at one of the wheels.

You might try removing the battery connectors for five minutes and replacing back.

If the codes do not disappear, please you might have to get a scanner to do that.

Cheers.
