Top 10 1999 Dodge Grand Caravan Questions & Answers

I am looking for a diagram that shows were the speed sensor is located on the transmission.Of a 96 Grand Caravan.

Big job.
Remove the dash. The heater-core is behind the center console.

radiator fan relay circuit.

Copy and paste it to a program that will allow you to make it larger.

If it's both the fuse blew, But if it's not, The switch is bad. If this was at all helpful, please rate. Thanks for asking.

I suggest you try one of those instant download manuals. My brother ( a mechanic) buys it when he can't fix some technical issue He buys from www.reliable-store.com . A lot
of mechanics actually do this. Website is very good for this. Must try it !!

Hi and welcome to FixYa, I am Kelly.
This is probably more information that you wanted but... have to cover all the possibilities:
If you are servicing a system that has leaked you have no idea how much oil it left in the system.
DO it right the first time......
The proper way to service it is to connect it to a recovery & servicing unit. Evacuate and test the system for leaks, then reservice the system per the specs below.
1999 Dodge Caravan:

. Low side gauge (evaporator suction): 10 to 37 psi.*
. High side gauge (discharge): 112 to 210 psi.*
. Refrigerant oil capacity (without rear A/C): 5.00 oz.
. Refrigerant oil capacity (with rear A/C): 7.40 oz.
. Refrigerant capacity (without rear A/C): 2.13 lbs. of R-134a
. Refrigerant capacity (with rear A/C): 2.88 lbs. of R-134a

*Sea level and ambient air temperature of 80 degrees F.

Hi there:
The engine coolant temperature sensor is a variable resistor with a range of -40 degrees F-265 degrees F (-5 degrees C-129 degrees C).

The engine coolant temperature sensor provides an input voltage to the PCM. As the coolant temperature varies, the sensor resistance changes resulting in a different input voltage to the PCM.

When the engine is cold, the PCM will demand slightly richer air/fuel mixtures and higher idle speeds until normal operating temperatures are reached.

The engine coolant temperature sensor is also utilized for control of the cooling fan.

Check this test procedure:

1. Turn the ignition switch to the OFF position.
2. Detach the coolant temperature sensor electrical connector.
3. Using a DVOM set to the ohms scale, connect one lead to terminal A and the other lead to terminal B of the coolant temperature sensor connector.

1. With the engine at normal operating temperature, approximaterly 200 degrees F (93 degrees C), the ohmmeter should read approximately 700-1000 ohms.
2. With the engine at room temperature, approximately 70 degrees F (21 degrees C), the ohmmeter should read approximately 7000-13,000 ohms.
3. If not within specifications, replace the engine coolant temperature sensor.
4. Test the resistance of the wiring harness between PCM terminal 26 and the sensor wiring harness connector. Also check for continuity between PCM connector terminal 43 and the sensor wiring harness connector. If the resistance measures greater than 1 ohm, repair the wiring harness as necessary.

should be underneath on the driverside on the frame near radiator small square flatbox with one wire connector three or four wires

I looked it up and doesn't have a route but if your able,here's a link to a repair book,it has a price but you will be able to repair your vehicle,I use them on all my vehicles,have 3.
