It all started yesterday. My a/c wouldn't blow any air at all. When I got home in the evening, my engine light came on and this morning I noticed that the drive felt like it was pulling and not shifting gears. Took it to get a diagnostic which read code p0888. Anything I can do to fix it? Or at least narrow it down?

 

Probably not a DIY repair, unless you are skilled electrically. Here is the conditions and diagnostic procedure:

Symptom:
P0888-RELAY OUTPUT ALWAYS OFF

When Monitored:
Continuously

Set Condition:
This DTC is set when less than 3 volts are present at the Transmission Control Relay output circuits at the Transmission Control Module (TCM) when the TCM is energizing the relay. Note: Due to the integration of the Powertrain and Transmission Control Modules, the transmission part of the PCM has its own specific power and ground circuits.

POSSIBLE CAUSES


FUSED B+ CIRCUIT OPEN
TRANSMISSION CONTROL RELAY OUTPUT CIRCUIT OPEN
TRANSMISSION CONTROL RELAY
TRANSMISSION CONTROL RELAY CONTROL CIRCUIT OPEN
TRANSMISSION CONTROL RELAY GROUND CIRCUIT OPEN
TRANSMISSION CONTROL RELAY CONTROL CIRCUIT SHORT TO GROUND
TRANSMISSION CONTROL RELAY OUTPUT CIRCUIT SHORT TO GROUND
POWERTRAIN CONTROL MODULE
TRANSMISSION SOLENOID/PRESSURE SWITCH ASSEMBLY
INTERMITTENT WIRING AND CONNECTORS








Hope this helps ya,

Hmmm.

Perhaps some low voltage problems? The clutch for the A/C maybe not holding and low voltage to the transmission are caused by a bad connection or ground problem?

Maybe not?
