Why doesnt my heat blower work in my 99 chevy 2500 cargo van ? it will get a little warm once I get up to 45 or 50 mph.

Have the tires checked for being balanced , Could be missing wheel weight .

This may be caused by many issues. Common fix is a basic tune up.

Hi Jim, If the vehicle is fitted with climate control it will have electronic management. However it can be wired by someone knowing electrical circuitry to by pass the control. It will save you some cash but will need manual control. Make sure whoever does the job knows what he or she is doing. Have a happy new year. Regards John

60psi cold / 30-45psi warm is ideal. I've seen (with that mileage) 45 cold/ 20 warm and that's acceptable - anything less start thinking about a new oil pump.

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

You have to drop the fuel tank. It is inside. Hope the tank is near empty, remove the 2 fuel fill hoses, you have two straps, lower tank, remove 3 wire connectors, and several more lines. Please use an ac delco fuel pump module. It may come updated with a new wiring connector to fix the old ones problem. If it does, you have to rewire the van following the directions.

jt\\it could be the water pump or the thermostat giving you problems
