Any help would be nice thanks soken wet snow storm
if it's a fullsize and it's like my 90 1/2 ton, then you might have the infamous "thermal actuator" and it might be toast or it's just taking a long time to engage. (whatta stupid design. my S15 Jimmy had a vacuum actuator that didn't do that, and the parts pricing for a new one is insane.)
Do a quick google for thermal actuator chevy...
