Heater blowing barely warm air.

Thermostat was done late lastnight after taking it out to get warmed to check the hoses. Sorry forgot to mention that. I'm about to take it on some errands so I'll see if anything changes.

Oil looks good under the cap and dipstick and no oil burning smell so I'm going to ignore it for now. It's not going to see much use this winter since I work at home anyways but heat would be neat lol.

I would definitely try the hose restriction as soon as you can.

Well heat got a little warm then heard some noise under the glove box area when i urned the fan on higher then lost what heat I had...so I'm assuming the blend door actuator is gone.

As mentioned before, they are a weak spot. Likely gonna need an 89018365 or AC Delco #15-72971 but would be best to post the last 8 digits of your VIN and reach out to @915_Tahoe and let him look it up to know for sure.

There's the vin..I have dual climate controls is there more than knew blend door actuator? Doesn't blow heat anywhere even the rear controls. I hear clicking and ticking noises when the heats on.
