    Help! A/C erratic on real hot days

    You can check the driver and passenger vent sensors with a Tech 2 to ensure they are in close agreement with one another. In addition, there is a cabin ambient air temp sensor near the ignition switch, (it has a little fan) an external temp sensor behind the front fascia, and a sun load...

    Delaminated roof

    If you mean the top panel, then it's made of SMC (Sheet Molded Composite.) For structural bonding, GM recommends the following adhesives: GM Goodwrench Plastic Structural Adhesive (P/N 89020330) Fusor 127 EZ Structural Adhesive (GM P/N 12345726) These aren't DIY repairs unless you have the...

    Help! DEAD IN THE WATER

    This sounds like a typical fuel pump problem. It's located in the left side tank, so it's a PITA to get at. There are fuel regulators and check valves in the fuel system, but your symptoms align with a faulty pump or intermittent pump ground. CC :wave:

    Turn signal volume

    This is an interesting question with an answer that surprised me. My first guess would have been a flasher relay wearing out. As we all know, there isn't anything normal about the XLR, when compared to what preceded it. The XLR doesn't use a (regular) flasher relay, and there isn't a whole...

    Manual shift issue

    The Driver Shift Control (DSC) doesn't have a lot going on as far as complexity. When the shift lever is moved into the DSC gate, it activates a set of switches to shift up or shift down. The switches are connected to the Transmission Control Module (TCM). A fault in this function is usually...

    First problem, Top Issues

    Today's scan tools are indispensable when troubleshooting the complexities inherent to modern automobiles. With the dual-bus, networked architecture of the XLR and it's many function-specific modules, they're even more so. As useful as scan tools are, the technical ability to interpret the...

    HVAC Blower Not Working After Car Wash

    I'm on vacation in the middle of Nowhere, and the only amenities happen to be Wi-Fi and mass quantities of beer. If no one steps up with a procedure (hint, hint) I'll respond with something next weekend. CCC :wave:

    GM Press Release sunvisor with Homelink?

    The HomeLink-equipped visor should work. The only input required is 12vDC power. As long as the connectors are the same, it ought to be plug-and-play. CCC :wave:

    HVAC Blower Not Working After Car Wash

    Your HVAC troubleshooting options are few. If the Controller (aka "The CJ2 Control Head") is illuminated, power is present, which is always the first thing to verify. The temperature sensors control airflow to each zone, and wouldn't affect the blower motor in manual mode. Since the fault...

    Price Goughing

    With a saturated marketing presence - eBay, Amazon, and all of the XLR sites where users go for parts and info, it wouldn't be hard to bring the unrealistic prices down being hawked by some of these people by undercutting them with more than competitive prices, good service, and word of mouth...

    Help! 2008 XLR Base - Wierd Things Happening

    Without looking through the lighting schematics, I would suspect a flasher relay or BCM-related problem. Check the BCM under the passenger foot well carpet for any blown fuses, signs of water intrusion, (from the right side of the windshield header) loose connectors, or bad relays - if you...

    Roof panel detached while driving

    Until the root cause of the problem (laminar flow, cracked bond joints from vibration, defective materials, etc) is fully understood, any vendor marketing a potential solution could face a potential liability nightmare if the top were to separate. Such is our society. . . As a vendor, I...

    Roof panel detached while driving

    The folding top's exterior (including the rear deck lid) is not made of aluminum. It's called SMC (Sheet Molded Compound) a rigid, thermoset plastic. I wouldn't characterize it as a flying razor blade, --though I wouldn't want it flying end over end into my car. Without pictures of the leading...

    Site Update: 2004 - 2009 Cadillac XLR: Service Bulletin: #PIC5558: Additional Diagnosis For Folding Top Temperature Messages Displayed On

    It would be cheaper to install a new thermistor at the pump connector (bypassing the original thermistor) than replace the whole pump. CCC

    Help! Electric issues

    No wonder you aren't getting anywhere with them. They've given up before they've started. How can they not find a part that they haven't even identified? This is an excuse masquerading as an explanation. I'd look for another dealer. CC
