The protocol is class 2 . Maybe your code reader is no good . 012 GM Class II Communications Data Link Connector (DLC) The data link connector (DLC) contains the following serial data links: • Class II • Entertainment and Comfort (E&C) The DLC also provides a power source for the scan tool as follows: • Unswitched voltage (B+) at DLC terminal 16 (circuit 1450) • Ground at terminal 4 (circuit 1450) and terminal 5 (circuit 1550) Class II Serial Data Link The class II serial data link allows the following modules to communicate data with each other: • Body control module (BCM) • Electronic brake traction control module (EBTCM) • Heater-A/C control (if equipped with RPO CJ2) • Instrument panel cluster (IPC) • Powertrain control module (PCM) • Inflatable Restraint Sensing and Diagnostic Module (SDM). The Class II serial data link allows a Scan Tool scan tool to communicate with the above modules for diagnostic and testing purposes. The Class II serial data link is located at the DLC connector terminal 2. Terminal 2 consists of the following circuits: • Circuit 1036 • Circuit 1037 • Circuit 1128 • Circuit 1049 • Circuit 1122 • Circuit 1132 Entertainment and Comfort (E&C) Serial Data Link The entertainment and comfort (E&C) serial data link allows a scan tool to communicate with the radio or the mobile telephone handset the remote CD player (if equipped). This communication is for diagnostic and testing purposes. The E&C serial data link is located at the DLC connector terminal 14, circuit 835. PIN #9 goes to the air bag module .

its more likely to be the drain hole for the shuttle, were the heater gets it air feed from there will be a drain for the water to get out, can get blocked with leaves etc, you may need to get your hand down there and pull out the rubbish and poke your finger in the hole to push the debris out.

Looks to me like the daytime running lamps control module suppy's power to the front turn signals .

There is usually a black plastic tube coming out of the firewall that goes to the manifold. If that looks good, I recommend you access the back of the control panel. From there, you can see if vacuum is getting to the panel and if it is being transferred to the various actuator lines as the mode selector is switched. I have pasted the procedure below. Buick Models CAUTION Vehicles covered by this guide are equipped with a Supplemental Inflatable Restraint (SIR) system, which uses an air bag. Whenever working near any of the SIR components, such as air bag module, steering column and instrument panel, disable the SIR. Fig. Heater & A/C control panel removal.

1. Disconnect the negative battery cable.
2. Remove the instrument cluster trim plate, using the following as a guide:
   1. Remove the instrument panel access hole covers from the instrument panel using a small flat-bladed tool. Remove the screws from each end of the instrument panel cluster trim plate.
   2. Remove the screws from the lower edge of the right lower instrument panel trim plate.
   3. Open the instrument panel compartment door.
   4. Pull the right lower instrument panel trim plate from the instrument panel.
   5. Pull steering column tilt level and tilt the steering column to the lowest position.
   6. Grasp the instrument panel cluster trim plate at the right edge, slowly pull an working from left to right, release the retainer clips. Lift the trim panel from the vehicle.
3. Remove the screws holding the heater & A/C control panel to the instrument panel and gently pull the assembly from the instrument panel. Detach the electrical connector(s) from the back of the panel. Some models may have a vacuum line connection that must also be removed.
4. Installation is the reverse of the removal process. Use care to make sure the retaining clips are properly seated and all screws are in place. This helps avoid rattles and squeaks later.

Do you know how to check for vacuum leaks ? Visually and physically inspect the following areas for vacuum leaks: • Intake manifold. • EGR adapter. • EGR valve. • EGR feed pipes. • Injector O-rings. There are videos on youtube showing how to do this ? I would suggest to you to have a diagnostic shop check engine sensor data with a scan tool that can display this data. ,Especially the mass air flow sensor . All the money you put into the parts would have had it fixed already .

Replace the instrument cluster. the LCD display is faulty.

Reads those codes again, these are not valid, it should be one letter and four numbers.

Getting that radio out of the dash is a chore. Taking the radio itself apart is worse. Have a shop give you an estimate.

Partial obstruction at the heater core?

Hi Bennie: I'd start by checking the fuse panel. There may be a separate circuit for the high beams. Cheers.

Not a mechanic but have heard similar from older cars and been told that the tappets need adjusting.
