A faulty transmission control module (TCM) most often causes limp mode with the gearbox stuck in one gear, harsh jolts when you select D or R, erratic gear changes, flashing PRND letters and a gearbox or engine warning light. However, the same symptoms are often caused by a low gearbox oil level, a weak battery, a poor earth or a faulty sensor. To test a transmission control module, start by checking the battery and reading the fault codes with a diagnostic tool that can talk to the gearbox control unit, then check the power supply, the connector, the oil and the live data. Below we explain the symptoms, the diagnostic steps and what the most common fault codes mean.

What the panel does
A worn panel often shows up as dead buttons or no backlight while the air conditioning itself works fine. That is why replacing the panel can be cheaper than diagnosing the whole system.
Fitment
We have several panels with different numbers for this model. The label number and the year decide, not the model name alone.
Signs of a faulty panel
- the panel does not respond to button presses,
- the airflow does not change direction or strength,
- the display shows wrong values or goes dark,
- settings are not saved after the ignition is switched off.
First rule out the fuse, wiring loom and connectors, because their faults look like a damaged panel.
