1) you must test the wires connector from corroded cables , clean it
2) Test the voltage for 12vdc for input to the coil of the relais.
3) If there are NOT, test the fuse for open and replacle, the fuse box in the hood motor, see the instruction name, and identify the fuse or c.breaker. and replace or repair.
4) see the diagram attached and use the logic sense for troubleshooting.
God bless you

SOURCE: how to replace brake light in 2008 chevy express cargo van

You have to remove the upper applique to remove the tail lamp, it is the trim panel above the lamp. I think it is held in place by two nuts/bolts but not sure. You have to have the rear doors open to remove it

SOURCE: Reverse and interior lights out, chevy express van

Fuse block under the hood. Driver's side, under the brake master cylinder. Number 18. TCB#2. Replace the fuse.

There is an under-engineered ground in the reverse circuit. If you back up with the dome lights on, it could blow that fuse. There should be some extra fuses under the cover of the fuse block.

98 chevy van A/Crelay will not cluch on uless you un plug and put back in then A/C cluch engages


Causing it to work just by unplugging the relay and putting it back in seems to indicate the relay may be faulty- lazy and doesn't want to work. Try a different relay and see if it works better.

When dose a timing belt need to be replaced on a 2003 express van?


This van has a timing chain, which should last for the life of the engine. The LS engines, which I'm guessing you have one of the 4.8,5.3,or 6.0L, use a high quality roller timing chain that is long-lasting, and won't give you issues. Also, having roller lifters, the camshaft puts less resistance on the timing chain, so the combination of a strong chain coupled with less resistance, makes for a reliable chain.

Bruce did you check the freon. if the pressure is not enough the ac clutch will not engage. If it is the freon you may want to use a leak detector from your local autoparts store before wasting freon.
