Ok New Problem

[Eastcoast SHO]

so this morning on the way to work my heater started acting funny, nothing was coming out, then out of nowhere it starts blowing out the air, it has been doing that ever since, would this be the blower motor on its way out? or is it something totally different?

when it starts blowing it works fine, it is just the matter of it actually blowing

i thought of a loose connection but where would that be? behind the controls? where is the blower motor located on these cars?

Try this..

Run the self test procedure.

Self Test
1. NOTE: Intermittent (run time) trouble codes will be deleted after 80 ignition cycles.
The remote climate control module is capable of displaying both self-test faults and intermittent (run time) faults on the integrated control panel. To obtain these codes, perform the following EATC on-board diagnostics test:
• On-board diagnostics should be run in ambient temperatures between 10° C (50°F) and 32°C (90° F). Record all diagnostic trouble codes (DTCs) displayed during diagnostic test mode.
• Turn ignition switch to RUN position.
• Push both OFF and FLOOR buttons simultaneously, then press AUTO within two seconds.
• The test may run as long as 30 seconds while the display will show a dashed line in the center of the display window.
• After about 20 seconds, a DTC will appear in the display. Refer to the Diagnostic Trouble Code Index to identify the proper diagnostic procedures.

Diagnostic Trouble Code Index
EATC On-Board Diagnostics New Generation Star Tester or Service Bay Diagnostic System DTC Description Action
Self-Test Faults (Inter- mittent) Run Time Faults
022 B1239 A/C Electronic Blend Door Actuator Short. GO to Pinpoint Test A .

024 025 B1249 A/C Electronic Blend Door Actuator Failure. GO to Pinpoint Test A .

031 B1251 In-Car Temperature Sensor Open GO to Pinpoint Test B .

030 B1253 In-Car Temperature Sensor Short. GO to Pinpoint Test B .

040 042 B1257 Ambient Temperature Sensor Short GO to Pinpoint Test C .

050 052 B1261 Sunload Sensor Short GO to Pinpoint Test D .

195 C2767, U2005 Communication Error Between ICP and RCC GO to DTC U2005.
115 U1073 Engine Coolant Temperature Signal Refer to the Powertrain Control/Emissions Diagnosis Manual.
125 U1341 Vehicle Speed Signal Refer to the Powertrain Control/Emissions Diagnosis Manual.

• To exit the diagnostic test mode, press the blue button. When the EATC system assembly is turned back on, the A/C air temperature control door will self-calibrate for 20 seconds.
2. If self-test is passed and no DTCs are retrieved, go to Symptom Chart to continue diagnostics.
3. If DTCs are retrieved, go to the Diagnostic Trouble Code Index to continue diagnostics.

Apparently there is a relay under the hood to look at read this and see if it helps..

When this happened to me, it was a bad relay. Check the fuse box in the engine compartment and make sure the relay isn't burnt out or doesn't have a bad sit to where it's moving around.

I thought the heater wouldn't blow air until everything is warmed up enough. Is the car up to temp when this happens?

That is only on auto. When you have it on a manual selection, it does what you tell it to do.
