1996 chevy s10 pickup blows hot air all the time. even with everything turned off.


In my case (1995 S10) it was as simple as the temperature control potentiometer. The pot contacts were crushed, God knows what breaks and shorts happened there. Replaced the pot and all works like a charm. 3ffe43e2-1688-4bb5-ad86-58f1c719150e.jpg

My 1994 Chevy Blazer S-10 is not blowing out any air when I turn the heater on...


Is the fan turning on? I assume so.. when you change the hot/cold selector do you hear the flaps inguage? could be the linkage there. Otherwise, check your coolant level - make sure your heater core isn't plugged (let engine heat up, then see if the heather both heater hoses going into the firewall are warm). If one is colder than the other, flush the heater core.

Where is the heater contol valve on a 1998 chevy s10 blazer. i get very little heat


There isn't one. There is always coolant flowing through the heater core. The blend door controls all of the heating and airconditioning.
Make sure the heater core is free flowing, most of the time the core gets plugged with rust and slug and does not allow coolant to flow through. You can take the hoses off the core and try and back flush it with a gardan hose.

1988 Chevy Blazer Heater Core Replacement


first determine if the heater core is located high or low by raising the hood checking against the firewall {by following the heater hoses to the fire wall} if it is high need to remove the dash. if it is low get on your back and start removing clips and screws no special tool needed.
