More information would help. Is the engine warming up normally? Stuck thermostat is possible. Is the coolant system full? Low coolant can cause lack of circulation to the heater core. Does the fan blow? Some of these systems have a vacuum operated water valve controlling coolant flow to the heater core. A failure of the valve or vacuum leak can cause this failure. In short, you need a mechanic to diagnose this failure.

Try checking the heater control switch/valve, sometimes located in line with the heater hoses (it is a fairly common defect). You may also have a clogged or bad heater coil. (similar to a small radiator) or maybe a fault in the heat system's controls.

Just follow the Upper Radiator Hose to the Block. The Hose will attach to a Bell housing on the Manifold. Remove this Bellhousing and the Hose. The Thermostat is Right underneath the Bell Housing. Reinstall the Same way that the Old one is sitting when you find it or it will not work Properly.

SOURCE: my 1992 cadillac eldorado starter went out about

Did you check the condition of the positive cable or the large red power cable going down to the starter solenoid, and do you have 12 volts at the solenoid when you turn the key to the start position, this will be the small wire and terminal on the starter solenoid, if this has all been checked I would test the starter solenoid itself next. If you are not getting 12 volts when turning the key to the start position, you should double check fuses, and then possibly the ignition switch. Hope this gives you some other troubleshooting choices. Good luck and Happy Holidays!

SOURCE: 1992 Cadillac Eldorado Froze up, Won't turn over

take plugs out pour oil into clynders and turn by socket and breakerbar on right side of auto after you take wheel off. turn with plugs off. it should turn freely once that oil get into the clynders if it turns great! Change oil. If not you might have frozen crank or something happened when it was parked for a reason. Good luck.

How do I get power steering fluid out of the master cylinder for the brakes on a 1992 Cadillac Eldorado

Use a suction gun and then rags and then brake clean. Flush the entire system any PS fluid that gets to the wheel cylinders will most likely destroy them. The master cylinder is most likely already toast.

Cadillac fuse boxes are located under the dash on the driver's side and also under the hood on the driver's side. That is the case on my 1997 Cadillac Deville. Check your manual, for your Eldorado.
