First check engine coolant level; if there is too little coolant in the reservoir, you should be alerted to the possibility that there could be a leak somewhere in your car's cooling system. Remove the reservoir cap and add coolant to the Full-Cold line, if a very short time after you refill the coolant reservoir the coolant level is low, there is a leak in your car's cooling system.

Engine coolant is used to heat the heater core and if the vehicle is low on coolant the heater core will stop working. The heater cannot produce heat due to the lack of heat from the engine coolant. Even if the engine is not over heating the coolant level can still be low.

Nest step, inspect Heater Control Valve that is used to shut off hot coolant from entering the core when the heater is in the off position. A heater control valve can be actuated by either a vacuum line or a cable from the vacuum heater control valve to the heater core. This hose should be warm; if not the heater control valve is stuck and needs to be replaced. After the repair has been made refill the coolant level and recheck system.

Also, keep in mind that Blower Motor (electrical motor) is used to push air through the heater and air conditioner system, if the Blower Motor fails it will not force air through the system. Ground a test light lead to a good ground source, like a metal brace under the dash, seat mount bolt or under hood brace. Turn the key to the on position; check the fuse in the heater or blower motor fuse panel with a test light. Then lightly touch the service port at the top of the fuse on both sides. If the test light illuminates on both sides of the fuse, the fuse is okay and working properly. If the fuse lights the test light on one side it is blown and needs to be replaced.

Finally, if you are unsure of the location of the heater fuse consult a repair manual. If the fuse condition is OK, position the blower speed to the highest setting. Connect the ground end of the test light to a known ground source. Then probe both ground and power feed wires of the fan motor. The test light should illuminate on only one of the wires (fan motor failed). If the test light illuminates on both wires the ground source has shorted. If neither of the wires illuminate the power source is shorted.

Hope this clues helps; keep us updated.

You didnt say what year and model, but you should be able to follow this link and find answers.

does it light up and not flash or does it just not light up?

Unfortunetly Cadillacs have way to many control modules anyway, So I would be able to tell you what this is just by numbers. And Cadillac is stingy with their parts and don't like to release them to parts stores, like chrysler. What is your car doing or not doing, maybe I can tell you what it is from symptoms.

The pistons do not compress like the fronts, they need to be turned to the right as you are pushing them in, like you are screwing them in.

Hello there,
Please follow the steps below to be able to replace the lamp,

1. Park the vehicle on a level surface. Turn off the engine.
2. Remove the four pushpins located on the underside of the protective shield on the front of the vehicle. Remove the protective shield from the vehicle.
3. Reach behind the front bumper area from under the vehicle to access the lamp housing.
4. Remove the largest bulb socket from the housing by rotating the socket counterclockwise. Disconnect the electrical connector from the bulb by lifting the two plastic clips at the base of the bulb.
5. Pull the burned-out bulb out. Replace it with a new bulb by pushing the new bulb directly into the socket. Reconnect the electrical connector to the socket. Place the socket back into the housing. Rotate it clockwise to secure it in place.
6. Reattach the protective shield to the front of the vehicle by reinstalling the pushpins.

Hope this helped. Goodluck Elect_Comp

Hello,

Power steering systems are actually pretty basic as far as operation, however pain in the **** when it comes to leaks. As read, you said you had leak in what you thought was in your power steering pump, and then found out it was the hi pressure hose that was leaking, Unless your car has some type of fuse that controls it in your fuse panel. (check owners manual, to see if you have a relay type of fuse that controls the electrical circuit that triggers the pump) if so, it could of got blown. However, I believe this is what has happened. When you had a leak in the power steering, you thought it was the pump, so you replaced the pump, which of course pump was probably bad because of lack of fluid circulation with a leak, it instantly will dry out, from high heat of friction from barrings, metal on metal with no fluid. Now, that being said, you put new pump on, but sense the leak was actually off the high pressure hose, means it is highly possible that your new pump, by driving it for even 10 minutes, with the leak of high pressure hose, could of cause new pump to burnout. So, at worse case example, you have burnt up new pump, because of the time you replace the high pressure hose might of already done the damage to the new pump. But, before you go that route of replacing again, the new pump, check all your wire connections that are triggering the pump. Make sure all connections are hooked up good, and making good contact, as even the pump has to have power supply to trigger it, and check to see if inline fuse (if has one) is good and of course as said earlier fuse box to see if as a safety feature, sense would be low on fluid with a leak if it blew the fuse that controls the electronics that go to the pump , make sure it is good. I hope this helps you in the areas to look. Places like AUTO ZONE, can look up your car and let you know for sure if your pump is controlled by a separate fuse and where it would be. Thanks Mike from Fixya

If it is an older cadillac, I have a solution for you. If not, this link will still help educate you. http://vatspasslockpasskeysecurityhelp.yolasite.com/

Sounds like a vacuum leak. this will affect the idle causing it to idle high but with no power (at idle) so almost dies at idle in drive, (under resistance) The knocking is likely your exhaust pipe shaking and hitting under car, cos of the engine shake.
Look for a vacuum tube hanging loose from around the intake area. Maybe trim off stretched end and reattach. May be able to hear it with engine running.

What king and type of battery? A delco battery ACDelco Professional 7-Year Battery Also available in 6-Year and 5-Year models50-month free replacement limited warranty* - one of the best in the industry!

If the ABS light is on, there is a problem in the ABS system that the computer has detected. Unfortunately, you need an ABS code reader to find out what the issue is. Could be as simple as a wheel sensor, or something more complex. I would take it to a repair shop that you trust and have them retrieve the ABS code(s). that way you can properly fix it. Disconnecting the battery for 15 minutes will make the ABS light go off, but if the problem hasn't been fixed it will come back on.

I would scan for BCM errors, you could have caused a voltage spike.
