Hi everyone,

 

New to the site due to a weird occurence in my 2002 Escalade. I'll be simple and to the point, and hope someone can help out or point me in the right direction.

 

For the past 2 weeks our SUV has had the heat coming from any vent, whether or not the fan is on, whether or not the temperature dial is set at 66(cold/blue) and it doesnt matter what position the fan/vent is in(feet, face, windshield defrost.

 

All of the gauges(oil, temp, battery) are showing as in the normal range. Gas mileage is the same, it runs/drives the same, have not changed the type of gas or oil. I'm trying to cover the basics here on how it is driving whether or not it is connected. I have not seen any messages in the message center in the panel.

 

I havent taken it into my local(reliable) auto shop yet as I wanted to have some information first on what it could be.

 

Thanks again for any and all help.

Most likely the heater control valve is stuck open. Or it could be the air mixing door stuck open or closed.

Not exactly sure on your Caddy but my 02 Silverado has both a hot/cold actuator and a mode control actuator that directs the air flow to whatever area is selected (defrost, etc.). The way you describe it though it sounds as either both actuators are acting up or possibly the control panel has gone south. I know the Tahoes are set up like my truck. Do you hear any clicking or binding noise when you turn the temp from hot to cold or vice versa?

After reading your post again does the air flow change from vent to defrost, etc. If it does I'd say the hot/cold actuator is stuck and needs to be replaced. Getting air blowing through w/ the fan switch off is normal on these vehicles by the way and if you do have an actuator stuck in the "hot" position then you will get hot air flowing out of your HVAC system in any position selected.

I can't help you, but will say, that really sucks. Having the heater blowing this time a year. Which, you probably don't live where it is as warm. :rolleyes:

No clicking noise at all between hot/cold/in between. And hot air comes out when it is on the front defrost(not that i need it now but still). And the heat is even more noticeable since the vehicle is black w/very dark tinted windows.

 

I appreciate the help alot :D

 

Sorry, I can't be of any help with your problem, but welcome to to the forum. :oops:

 

Thank you so much! It seems little things are breaking down or off at the same time on my Caddy so i'm a bit PO'd about it. But once I buy a car I end up keeping it till it dies or is on life support ;)

 

And i love my Escalade even with these horrendous gas prices. I live in western Pennsylvania and right now it is at $4.29/gallon for mid-grade.

I'm still a lil confused....Is your HVAC controller functioning properly w/ the exception of giving you only hot air? Meaning that whatever mode you select the air flow is directed to the appropriate vents. If indeed it is functioning properly but you only get hot air then I suspect the hot/cold actuator is FUBR (old military acronym) and needs to be replaced.

      OCI, not when but why?

      By KARNUT · Posted

      It seems fine because it pulls everything out of a hot engine. I’m not going to worry about a thimble full with 5K oil changes with synthetic oil. Every other oil change is at Honda they pull the plug. I watch them through the process. It turns out going to Honda what amounts to their normal oil change intervals.

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.
