To replace the defrost vent on a Chevy S10, first, disconnect the battery and remove any necessary trim pieces from the dashboard to access the vent. Next, detach the old vent by unscrewing or unclipping it from the ductwork. Install the new vent by securing it in place and reassembling any removed components. Finally, reconnect the battery and test the defrost function to ensure proper installation.
the defrost vent should just pop out by taking a screw driver underneath the sides of the vent cover and prying it up.
What causes heat to only come out of the defrost and vent but not the floor of a 1995 S10 Blazer?
Check under hood for a broken or disconnected vacuum supply line.
Check under the hood for a broken or disconnected vacuum line.
Most likely a vacuum leak turn on the vehicle and listen in the engine compartment and listen for the sound of air escaping from a hose. Replace the hose and your problem should be fixed (i had this happen to my 1993 s10 blazer)
The vent door actuator is operated from the engine vacuum. If the vent control doesn't respond to your demand check the vacuum supply line from the engine, it may be damaged or disconnected. Do this before you tear apart the dash and HVAC box.
on the dash below the windshield.
The center vent, or defrost duct.
It would probably be cheaper to buy another one of whatever you dropped down there. The defrost grill will remove, it just snaps in but if the item is not visible down the defrost vent, the entire dash assembly would need to come out to gain access to the duct work.
my 1998 gmc jimmy has no floor heat but i have defrost and ven heat
You replace the brakes on an ABS S10 the same way you replace brakes on a non ABS S10.
check your vacume lines, they tend to dry rott and not hold vacume. (under the hood anlong the firewall and to your intake manifold, it your selector for vent or defrost is run off vacume, if that works and you have air coming out your vent then your heater core could be bypassed Look for a plastic vacuum storage ball. The lines to this are probably dry rotted.
