Top 10 1999 Dodge Intrepid Questions & Answers

the relay is under the dash buy the steering column. it is a small black plastic square box

It is located on the left side of the engine down where the lower rad hose meets the engine block. It is fairly difficult to change.

Error code Number P1684 Battery Disconnected Within Last 50 Starts. Check battery and connections.

Major issues with the 2.7L motor. design flaw causes oil to hang in the heads and "cook" creating sludge. Sludge builds until the passage to the timing chain is blocked starving the chain and causing near instant failure...this is a "rattling" or Roulette wheel sound. The 2.7L is an "interference" type engine. When the chain breaks or jumps, the cams stop in position thus leaving the valves wherever they may land. The pistons keep on moving though....and kiss whatever valves happen to be open. Bye Bye Motor. Using Synthetic oil EARLY and exclusively cures the sludge issue. Replacing the timing chain and components at interval is crucial...don't wait for it to break or jump!

Sure sounds like a blend air door problem. The rotary temperature knob moves a cable that moves the blend air door. There is a bushing in the housing that likes to break and will either leave the door closed no heat or open heat when a/c is on. TSB 8506-01 covers this problem.
A/C - Can't Adjust Temperature Output Control

July 11, 2006
2012432





Affected Vehicles
Condition
HVAC, Temperature Output Control Cannot Be Adjusted
Customer states cannot adjust temperature and/or A/C is not cold.
Technical Background
The blend door control lever moves freely, but the blend door does not operate.




A bushing that fits on the lever may have a broken tab/clip, -arrows-, as shown.
This tab/clip may cause the bushing to fall out of the fresh air housing which can result in the door becoming inoperative and result in undesired air temperature.
Production Solution
No production change required.
Service Procedure
Tip:
In the past the entire fresh air housing was replaced because the bushing was not available as a separate part. The bushing is now available as a separate part.
The bushing can be accessed from under the center console.



^ Remove the panels near the foot wells at the passenger side of the console, -arrows-, as shown.
See Repair Manual, Body-Interior, Repair Group 68 - Interior Equipment for removal procedure.



^ This will expose the location of the control lever, -arrow-, as shown.



^ Re-bolt a new bushing onto the lever, -arrow-, as shown.
^ Re-insert the bushing with lever onto the blend door until it is firmly secured in the housing.
Tip:



A mirror can be used to aid in identifying the orientation of the blend door when re-securing the bushing in the fresh air housing, -arrow-, as shown.
^ Reinstall panels.

Hope you are good at working in tight spots and with mirrors. I just did this job 2 weeks ago. It took 1 hour and was really a pain in the B==t working upside down with a mirror through a 1 inch hole. Hope this helps and Good Luck Happy New year and thanks for using FixYa.

Drive it some more. Has the battery been disconnected/replaced recently? The Inspection station should be able to print you out a drive cycle to get the monitors ready also.

The "Vehicle Speed Sensor" signal is generated by the transmisson output speed sensor. That is the one located at the rear of the case. It is externally mounted. That supplies "vehicle speed" info to the other On-Board Computers. The input turbine speed sensor is located just behind the bell housing area of the case. I believe the trans controller is the only module that needs that info. The Crank Position Sensor give engine RPM info and it is located on the bell housing near the engine block. I hope this helps.

Below are the steps needed to remove the catalytic converters. You may be able to first remove the band clamp from between the converter and the exhaust manifold, then loosen the rest of the system and to get enough clearance to slide the converter towards the front of the vehicle but you will need to first remove the clamp that holds the converter to the rest of the exhaust. Hope this helps
_______________________
Both Catalytic Convertors

First you need to raise the vehicle.

Next, you need to pry the insulators from the support brackets and support the muffler and tailpipe with jackstands.

Then, loosen the the catalytic converter down pipe-to-front resonator clamps and separate the front resonator from the converter down-pipes. Carefully lay the free laying exhaust on the ground.

______________________
Right Catalytic Converter

Then, remove the down-pipe-to-transaxle bracket nut, loosen the clamp and separate the extension pipe from the converter.

Next lower the vehicle and remove the air filter and intake ducts. Disconnect the wiring harness for the O2 sensor and the remove the sensor.

Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment. You may need to replace these clamps after removal because you need to pry it apart and they will leak when you reinstall.

_____________________
Left Catalytic Converter

Now disconnect the wiring harness for the O2 sensor and the remove the sensor.

Next remove the down-pipe-to-transaxle bracket nut

Finally loosen the band clamp at the exhaust manifold and remove the converter from the engine compartment.

Try "cycling the key in the passenger door lock. Turn it all the way to the right and all the way to the left.

I'm assuming that you are talking about 2.7L, the check this procedure...

Removal & Installation - 2.7L Engines

1. Drain the engine oil.
2. Remove or disconnect the following:
   Crankshaft damper Timing chain cover Timing chain Crankshaft sprocket Oil pan Oil pickup tube and O-RING Oil pump

To install:

Fig. Oil pump mounting bolt locations-2.7L engine

1. Fill the oil pump rotor cavity with clean engine oil.
2. Carefully, install the oil pump over the crankshaft and into position.
3. Install the oil pump mounting bolts and torque to 21 ft. lbs. (28 Nm).
4. Lubricate the new pickup tube O-ring with clean engine oil and torque the pickup tube mounting bolts to 21 ft. lbs. (28 Nm).
5. Install or connect the following:
   Oil pan Crankshaft sprocket Timing chain Timing chain cover Crankshaft damper
6. Fill the engine with clean engine oil.
7. Start the vehicle, check for leaks and repair if necessary.

Hope helps (remember to rate this).
