Can he tell if the heater core is clogged with the heater hose temp check? After car's warmed up with blower on high heat feel the temp of the inlet hose and outlet hose and see if the outlet is almost as warm as the inlet. That indicates rapid enough flow that the water isn't being completely cooled off with air blowing over the heater core...

Okay, #1 cylinder on a '64 engine is up front, on the DRIVER's side.
#158 of 165 Auto Door Locks / 90 Deville
Sep 30, 2006 (12:33 am)
My door locks don't work with the switch - (they work manually and are fairly stiff to push) I can push the lock button and it does have that click sound but the lock slide does not move enough to unlock/lock the doors - I thought that the doors should lock when you drive off like my 95 Buick
also my security light comes on when I turn off the car but if I reach inside the window and unlock/open the door nothing goes off (horn etc)
any help would be appreciated
#159 of 165 2004 Deville oil consumption
Oct 03, 2006 (5:50 am)
We have 2 04 Devilles used for a livery service. One runs perfect but the other has a major oil consumption problem. Cadillac is telling us that this is "Normal" The car uses over 3qt of oil in less than 3k miles. This is all highway travel. The Deville only has 50k miles on it and is under warranty. Has anyone else had problems with Cadillac taking care of this under warranty.

The rings are carboned up.
Take the car out and run it floored. Let it hit all the max rpm 's in each gear. You will probably see lots of black smoke coming out the tail pipes. Do this several times. Let it coast down after each run-up, this also helps break the rings loose.
I'm not responsible for possible speeding tickets, since this process should take you up to 90mph or so each time, which is probably only the shift point from 3rd to 4th gear. 3rd might even take you past 90mph.
Anyway, the only other procedure (and your dealer should know about this) is to use a 'kit' (cleaner, adapters for removing cleaner, etc) and process documented by CAdillac. It pours a cleaner into the cylinders thru plug holes, let it set, vacumn it out, run the car, change the oil, run cleaner thru it again, run it, change oil again.

I have a 1975 Cadillac Coupe deville and I can't get the locks to work. Neither the electric switch or the button locks work. The wires running to the switches seem to have a current running through them. Can anyone give me some advice on how to fix it?

Do you mean the manual stalks on the rear, top of the doors?
If these won't move, it sure sounds like a manual linkage problem to me. There are lots of little metal rods, clips, levers, etc in there. In 32 years stuff wears out, breaks, or comes unclipped.
You are going to have to pull door panels and visualy inspect this sucker. A power actuator (just a big reostat) might be dead or jammed, but I would think the manual button would still work....
#163 of 165 93 deville heating problem
Oct 18, 2006 (5:38 am)
Strange problem...i have heat blowing out on the passenger side but cold air blowing out on driver's side. Mechanic checked blend doors (as he called them) and they were opening and closing properly, he said. He also said that maybe there is another door way up inside that he can't get at. At 80 bucks an hour for labor, am reluctant to just drop off and let them run up a bill playin with it. Any advice?
