Hello and welcome to justanswer.
This problem is fairly common and can be caused by a poor connection in the vehicle harness. I have included the details below in a technical service bulletin. Please let me know if you have additional questions.

This bulletin is being revised to update an illustration. Please discard Corporate Bulletin Number 03-08-45-003C (Section 08 - Body and Accessories).
Some customers may comment that the vehicle is exhibiting one or more of the following conditions:
|^||Reduced power |
|^||Transaxle not down shifting |
|^||SES light on |
|^||Buzz noise from door speaker(s) |
|^||Speaker(s) inoperative |
|^||HVAC blower motor inoperative |
|^||A/C compressor commanded OFF with vehicle speed (evaporator temperature sensor circuit 719 and/or 731 may be open) |
These conditions may be intermittent. Diagnostic Trouble Codes (DTC) P0223, P0504, P0700, P1228, P1271, P1280, P1599, P1779, P1791, P2119, P2101, P2128, P2135, or P2138 may also be present.
The instrument panel/body inline connector (black 40-pin electrical connector), located behind the left hinge pillar garnish molding, may have bent or corroded terminals.
Disconnect and inspect the instrument panel/body inline connector (black 40-pin electrical connector). If necessary, replace damaged terminals and apply dielectric grease to the connector.
|1.||Starting at the left hinge pillar garnish, pull upward to disengage the attaching clips. |
|2.||Reach under the instrument panel and pull upwards to disengage the additional clips and remove the molding from the vehicle. |
|3.||Disconnect the instrument panel/body inline connector (black 40-pin electrical connector). |
|4.||Inspect the connector for bent or corroded terminals. |
Important: If no corrosion or bent terminals are found, proceed to Step 7 and follow trouble code diagnostics in the service manual or SI.
|5.||Remove any bent or corroded pins from the connector. |
|6.||Install the new terminal cut lead (verify correct size using connector/harness face views and electrical schematics in the appropriate service manual or SI). |
|7.||Pack the connector terminals with dielectric grease in order to prevent any further corrosion. |
|8.||Connect the instrument panel/body inline connector (black 40-pin electrical connector). |
|9.||Install the molding.|
