You should disconnect to alarm system. There is a hidden bottom under steering column. Keep push it 5 or more seconds...
Where at under the steering column is the hidden bottom at. What would make it have no giddy up from low speed but it has giddy up after 30 miles per hour
This is likely a miscommunication problem between the alternator regulator and the PCM, Powertrain Control Module due to an aftermarket or reman alternator. You need to find a new OEM alternator or a used OEM alternator. Or an alternator that was remanned but left the original regulator in place. The PCM communicates every 15 seconds or so with the regulator to control the alternator output. When the communication is corrupt, the regulator goes into default at about 13.7 volts or it can go to overcharge at 17 volts. Either scenario causes the lights to flicker. Connect a voltmeter to you cigar lighter socket with an accessory plug that you modify, and monitor the voltage readings. Normal voltage with engine running is just over 14 volts.
