    1998 Deville's frozen rear brake piston

    Turned out that a $12 wind-down tool and $24 pads fixed it all. So much for an $800 caliper job at Firestone. In March 2011 I went in to get 2 leaky tires replaced under warranty, and they gave me a $700 list of other things to replace... funny, the calipers were no longer on the list...

    1998 Cadillac Deville alternator issue

    I usually show 14.2v on the dashboard voltmeter. As of yesterday, it shows 13.6v. And every 30 seconds, it drops to 12.0v for about 5 seconds. IPC B1552 is the only code. What do you think?

    1998 Deville's frozen rear brake piston

    Trying to change the pads, but the pistons won't retract. The Firestone people said that the pistons or bores may be corroded, so you can't screw them fully open. Anyone have suggestions? Thanks.

    A/C pressure?

    There seems to be plenty of 134a in there now. Maybe the pressure sensor is dead. 135 viewers and no one has a clue about the correct pressure?

    A/C pressure?

    update 2 Decided to check my Crown Vic's a/c pressure... and the gauge showed that it had 45psi (like the Deville), but it dropped quickly to 25psi as soon as the compressor engaged. Soon after, the clutch would disengage because of low pressure. Ergo... maybe my gauge is off and the...

    A/C pressure?

    update I added R-134A to bring the pressure to 45psi (max. safe pressure), compressor still won't turn on. I also swapped the fuel pump and a/c compressor relays, in case the a/c relay was bad. Wrong again. Both relays are fine. The display says that the A/C Pressure is Low. Could I...

    A/C pressure?

    1998 Deville gave "low a/c coolant" message recently. Now won't go from ECON to AUTO and stay there. Looks like time for a recharge. But my cheesy gauge says 35psi in the system now. What is the correct psi?

    1998 DEVILLE's idle is loco after Emissions Test =================================== Immediately after our yearly emissions test (this year they hooked up the scanning computer), idling problems started. Last night it was idling at 2600rpm when I parked in my garage after a 10 mile drive...

    Hibernating '98 Deville ?

    My '98 Deville occasionally goes into "hibernation mode" after being parked. Meaning: battery power is evident in the trunk closer, but the dome light is dead upon opening the door and the car is nonresponsive to the remote... ...until you turn the key to ON. Then everything wakes up...

    ABS sticking ???

    For a month or so, it seems that the ABS braking system is constantly activated. The brakes are pulsing with every stop. My mechanic said the pads are fine, and he's seen the Deville ABS stick before. What can be done???

    Turn Signals Dead?

    My 98's turn signals went screwy yesterday and pooped out over about an hour's time. At first, they'd blink too fast... then would only work if you held the stick just so... now neither work at all. I got a replacement switch at Advance Auto. I need to remove the steering wheel (I have...

    Leaking Upper Oil Pan ?

    No, we're not sure yet. My mechanic just said that in his experience, it's never the oil pan.
