Bought this van at 87K, had a head gasket done at a dealership right away. Mostly used for Hwy driving until recently. Now it is used for US Mail delivery, about 100 miles per day, 45 miles at slow speeds. I maintain it well.

Yesterday, the engine fans ran all day, would not shut off. Disconnected the battery at the end of day, the fans were not going to shut off. Today, I had it running for an hour at idle, did not develop the problem, the fans never started, the needle in the dash was normal. I don't think the car returns coolant to the jug.. How do I check the coolant sensor and the fan relay? What do they look like? Your take? Maybe a coolant system pressure leak?

I have 1 day to work this out.

Also, never have been able to get either washer pump to work. No clicking when I push the button. The owners manuall tells me there is a self resetting fuse, has to go to the dealer to fix that. Is there a way I can service this?

The exhaust system seems to be in real good shape, no leaks that I see. The van runs with a sputtering sound, but it runs good, the tailpipe is pretty clean. There's a leak somewhere, I have not found it. No codes I pull up relate to that. I get #12 & #55, hi and goodbye.

This van really has to work every day for the next month. Help?

Thanks,
Mike

(Most common a bad relay )
for the fan to be on and not shut off even after engine of would be the fan relay

fan relays and PCM test

Turn ignition on. Check voltage at Gray wire of radiator fan relay, located on inner left front fender. If battery voltage is not present, check for open or shorted Gray wire.
If battery voltage is present, connect jumper wire between Gray wire and Dark Green wire of radiator fan relay. If fan operates, go to next step. If fan does not operate, check for open or shorted Dark Green wire between radiator fan relay and fan motor connector.
Check for loose connections at fan motor and fan motor relay. If all connections are okay, check for DTCs. If PCM detects a problem with cooling fan, a RAD FAN RELAY CIRCUIT DTC will be set.
NOTE: For additional information on DTCs and trouble shooting using DRB scan tool, see appropriate
If DTC indicates RAD FAN RELAY CIRCUIT, turn ignition off. Disconnect PCM harness connector. Check resistance between PCM connector terminal No. 73 (Light Green/Dark Blue wire) and ground. If resistance is less than 5 ohms, repair short to ground in Light Green/Dark Blue wire. If resistance is 5 ohms or greater, go to next step.
Check resistance between fan relay connector terminal No. 2 (Light Green/Dark Blue wire) and PCM connector terminal No. 73 (Light Green/Dark Blue wire). If resistance is greater than 5 ohms, repair open in Light Green/Dark Blue wire. If resistance is less than 5 ohms, replace PCM.

Washer pump
The front delay and washer systems are controlled by the Body Control Computer (BCM). These models are also equipped with a rear wiper/washer system controlled by the BCM.
locate the pump at the bottom of washer tank disconnect and check for power and ground with a helper holing down the switch for you if you have power and ground motor no good
if not locate BCM and disconnect wait few and reconnect and it that didn’t work we need to check the switch let me know
