How to verification and bushel

EASY but not promising

1 check into the 40A fuse in the fuse box under the hood on the drivers side. The inside of the lid to the fuse box will tell you which unitary it is.

More difficult but a bit more likely

Check into the coolant temperature sensor at the top of the engine

1. With the keystone OFF, disconnect cable harness connection from coolant temperature sensing element commonly right following to where the rangy radiator hose exits the top of the engine where the thermostat housing is:
   

Fig 96 Engine Coolant Temperature Sensing element Connector

1. Connect a high input impedance (digital) volt-ohmmeter to terminals A and B (Fig. 96). The ohmmeter should read as follows:

·

• Normal operating temperature or so 200°F ohmmeter should interpret or s 700 to 1,000 ohms .
• Room temperature just about 70°F ohmmeter should read approximately 7,000 to 13,000 ohms .

1. Mental test the resistance of the wire tackle between the PCM connector terminal 26 and the sensor harness connector. Besides chip for continuity 'tween PCM connexion terminal 43 and the sensor harness connector.

·

• If the resistance is greater than 1 ohm , repair the wire rule as necessary.

26 – sensor rule = 0

43 – sensor harness = 0

Learn the relay for the fans: (MOST LIKELY FAILURE AND MOST DIFFICULT)

If the Radiator fan control mental faculty has failed you will need to substitute it with a new 1 there is no mode to furbish up it.

To supercede the faculty,

The radiator fan electrical relay is located below the left presence headlamp faculty. The headlamp faculty must beryllium distant to access the electrical relay.

Remotion

1. Agaze hood, disconnect and sequestrate the battery negative cable.
2. Transfer the leftover side headlamp medulla oblongata from the headlamp housing. Refer to Lighting and Horns.
3. Remove the left headlight module.
4. Remove the cover over the electrical relay.
5. Disconnect the relay connective.
6. Carefully drill out the ii retaining rivets.
7. Hit electrical relay from vehicle.

INSTALLATION

CAUTION: The relay mounting location is designed to dissipate heat. Check the relay is properly attached to prevent relay "thermal" shutdown and relay equipment casualty, sequent in mathematical engine overheating.

For installation, reverse the above subprogram using new rivets included with the solid state relay

To remove the headlamp

Remotion

1. Release hood latch and open hood.
2. From inside engine compartment, take off nuts retention headlamp module to radiator closure jury.
3. Bump off screw holding top of module to closing panel.

1. Remove headlamp mental faculty from radiator gag law panel.
2. Gulf wire connectors from dorsum of headlight module.
3. Separate headlamp mental faculty from vehicle.

INSTALLATION

1. Identify headlight mental faculty in position on vehicle.
2. Connect wire connectors into back of headlight module.
3. Place headlamp module in put back on radiator closure panel.
4. Install balmy to hold headlamp module to radiator shutdown panel.
5. Install screw to keep down top of module to closure panel.
6. Verify headlamp operation and alignment.

Be sure to inspect the connector for the module and for the fans for melting and burning, if you incu some it must live repaired or the new components leave fail.

More complicated but thorough information:

I have a 1998 Dodge caravan and a p1698 troubleshooting code. Where should I start. Also a radiator fan relay switch that has a bad association operating room bad electrical switch. Where is the switch over?

Hello and welcome to Just answer.com, Super mechanic here. About your fomite.

There is a fan causative relay, which there was a retrieve for happening some.

To: XXXXX XXXXX and Chrysler-Plymouth Dealers

Subject:
Customer Satisfaction Notification # XXXXX — Radiator Fan Electrical relay and Reprogram Powertrain Control Module

Models:
1998 Model Year Dodge Caravan and Grand Van; Plymouth Voyager and Grand Voyager; and Chrysler Town & Country (NS) Vehicles Equipped With a 2.4L, 3.3L or 3.8L Locomotive ("B", "G","R" or "L" in the 8th VIN Position) Built Through:

^	November 26, 1997 (MDH 112623) at the St. Louis Southwestward Assembly Plant ("B" in the 11th VIN Position)
^	December 1, 1997 (MDH 120109) at the Windsor Assembly Institut ("R" in the 11th VIN Position)

The radiator fan relay on about 150,000 of the preceding listed vehicles, May not turn along the radiator cooling fans. This may causal agency the engine to overheat. To correct this condition, the radiator fan electrical relay must be replaced and the Powertrain Mastery Module (PCM) must be reprogrammed (flashed).

On the trouble cypher,
