I have an 03 MV, recently the traction control light and ABS lights have started coming on randomly. It seems to be preceded with the traction control light blinking, lose of power from the gas pedal, and a clicking noise under the passenger side of the dash, I assume that is where the relay is. This symptom only seems to happen when making a right turn of varying degree, either a shallow curve or a hard turn. If I let off of the gas the light will stop blinking and I get power back. However, not too long after this and randomly both the lights will come on and stay on.
Not sure if this is a related symptom, again just recently on engine startup air won't blow through the front air vents. I have to drive for about 5-10 seconds and then you can hear a click from somewhere under the dash and then the air will blow normally. I suspect this is a vacuum leak. Within the past year or so I replaced a lot of the vacuum line. But there must be more somewhere if this is the case.
I searched online for a few days and the only solution I found was to clean the MAF sensor as that apparently can cause some problem. Oh, when this happens it doesn't give any OBDII codes. Any help would be appreciated thanks.
