Well, I think you have quite a bit wrong here.
If he truly has blown head gaskets on a Northstar, there is more to it than replacing the gaskets and using new head bolts.
He will have to have the motor pulled. This is the only way to make the following repair because you cannot reach the rear head to do this.
The heads have to be pulled. (If you do this, do both heads.) Just unscrewing the head bolts will many times damage more of the bolts, stripping the alumium threads. Then the motor has to be 'Timeserted'. This is a package which has a metal jig (which can be reused, shops that have done this before will already have this) which is bolted to the motor and all the bolt holes are drilled out. Then threads are re-tapped into the holes. Then a special Timesert insert is screwed in. Then the head can be put back on with a new gasket and new bolts, which screw into the new insert. The heads themselves usually are fine, they are almost bulletproof, there is no milling needed. Then the motor can be put back in.
This is usually around a $3,000 job. The main part is labor. Pulling the motor (and transmission together), drilling, tapping, assembly and then putting the motor back into the car. Parts are only something like $500-$750 or so, including a Timesert kit and the needed gaskets, etc.
When you are looking at a $6,000 car (1999 Deville), you really need to think about putting $3,000 into it. A lot of beautiful Cadillacs are scrapped because of the cost of a head job.

My DTS is approaching 100,000 miles - time for tune up. What else should I expect or need other than engine tune up? Do the electronic shocks wear out like the older shocks/struts?

What are you expecting to service? What does your owner's manual say?
If it were mine, I would do:
-Plug wires (may not have these, may be coil-on-plug)
-Drain transmission fluid (don't flush. But be sure whoever does this knows there is a second plug after you pull the pan that need to be pulled.)

Perhaps I should have been more spcific - What can I expect the Cadillac Service Manager to suggest needs to be done at 100,000 miles. Again- are shocks/struts on the agenda?

He may suggest that any liquid near the car, including your Slushy drink in the cup holder be changed.
Rotate the air in the tires.
The liquid change should include the turn signal fluid.
Grease the muffler bearings.
What's so hard about looking at the service items in the owner's manual for the 100,000 service?
The list I previously gave should cover it.
I can't say much about the struts. Is the car banging when going over bumps? If so, there my be a need for struts, or other suspension components, such as sway bar linkages. If the struts are electronically controlled, there will be sensor in there that tell the computer if they are working ok. If they are not, there will be a check engine light turned on and/or a message displayed in your Display Information Condition (DIC) on your dash.

99 Caddy Deville. the trunk release and fuel door release have stopped working, no clicking noise either. remote key buttons won't open them either. doors do open with remote. I've replaced the radio/phone and convenc fuses in the trunk but it didn't help. could it be another fuse ? or something else?

Does your have the 'Valet' button in the edge of the glove box?
If so, you may have pushed this. It disables opening the trunk.

I own a 98 caddy deville my headlights come on by themselves only in daytime when I put the car in gear only and at night they dont come at all and my dash says headlights suggested does any one no whats my problem

Mar 28, 2008 (6:32 am)
I think that the in the daytime you see the daylight running lights. Are you sure that the automatic headlights on switch is turned on? If it is then it has failed.
