How to change 2003 waterpump chevy van 2500 series
Instructions too long to write here. you can find them in any cheap manual such as haynes. Most important part of job is to make sure you remove ALL of the old gasket on block before replacing with new, and to re-check all hose connections after you run it for a while to prevent leaks. Make sure you can remember where belt routing is so that you're not stumped when you go to put it back on.If it overheated, it's wise to replace thermostat...they get weird after overheating.
Check engine light for 04 express 2500 van
Yes that is correct.There is also a coil that fires the spark plug for each cylinder.There are specific tests for each component so you can find out which part is bad.compression could also be an isue not likely if the problem came all the sudden.
Fan runs when engine is not
the first thing to test is the [bitron] sensor its on the side of the radiator this sensor overides the ign system.a simple test can soon establish if this the fault.to test ;1 disconnect the wiring plug from bitron switch ,bridge the two contacts in the wiring plug useing a lenth of spare wire and switch the ign on if the fan now operates the switch is faulty [replace]hope this helps you.adrain
Check engine light starts blinking going up a incline
You have a cylinder misfire. That is the only thing that will flash the check engine light. With the van running spray the plug wires with water. Watch and listen for arcing. If there is, replace that or all the wires. It is possible for new wires to be bad. Next check the cap and rotor buy spraying them with water, than removing and looking inside for signs of burning or anything that will hinder the spark. Last check the spark plugs for carbon tracking (small black lines in the porcelin), caused buy hair line cracks. If you dont find any thing, check it again. With no other codes it is very unlikley that anything else is causing the misfire.

Door very stiff won't close tight
I have the same problem with the side doors of my 04 express. I put penetrating oil on the hinge pin with a hypodermic needle (hard to find). It is important that the oil gets into the hinge. I bent one set of hinges and broke a hinge because I waited too long to oil the hinge. The door may not close correctly because the hinge may be slightly bent. Keep all other hinges well lubed especially during the winter months when the hinges can be exposed to road salt. Fixing a bent hinge is difficult at best.
Engine will not start.
HI............
Check if the SECURITY LIGHT is Blinking or on.
Or off.
Let me know if you have replaced any electrical part.
Or if have replace the lock Cylinder.
I will try to help you.
Thank you.

How to remove 2016 Chevy Express overhead climate control panel?
The rear auxiliary heater and air conditioning control replacement procedure starts with removing the HVAC control assembly bezel (trim) from the headliner. Next, the headliner must be lowered in order to access the rear of the HVAC control assembly. This requires removal of the windshield garnish molding (A-pillar trim) and upper pillar garnish molding (B-pillar trim) at a minimum. You may be able to gain the necessary access by allowing the headliner to "hang" slightly rather than removing it entirely. After this is done, the electrical connectors can be disconnected and the HVAC control assembly can be removed from the headliner.

Mechanic check fuses and instal new back up switch and steel not working reverse lights,backing camera and dome lights???thi is about chevy express 2500 2007 year
You didn't take it to a good enough mechanic . Backup Lamps
The B/U LP 20 A fuse in the underhood fuse block supplies battery positive voltage to the normally open park neutral position (PNP) switch. When driver places the gear selector lever is in the REVERSE position, the switch closes and the voltage is from the switch to the powertrain control module (PCM). The PCM signals the BCM on the class II serial data circuits that the backup lamps are requested. The BCM supplies voltage on the backup lamp supply voltage circuit to the backup lamps and to the automatic day/night mirror. The backup lamps are grounded at G401. Voltage for the backup lamp supply voltage, without RPO YF7 the courtesy lamp supply voltage, and with RPO YF7 the courtesy lamp high control circuits is from the TBC 2 fuse 18 in the underhood fuse block directly through the BCM to these circuits.
