Review: It fixed my problem, 1994 GMC Sonoma - For years I've dealt with my truck only having airflow at the defrost blowing on the windshield. No matter what setting I put the air on, it only came out at the windshield. Now this truck is 29 years old, lots of things no longer work, like the A/C or the light at the vanity mirror (which I cut the wire on because it would not turn off anymore and had drained and destroyed a nearly new battery and who needs a light on the vanity mirror?) and I usually drive with the windows down anyway, but it bothered me that I knew this had to be an easy fix. I checked out some youtube videos and narrowed it down to this part or something way more involved that required a smoke machine and tearing out the dashboard which I am not doing because I'm a 5'2" woman and the one time I removed the door panel to replace the side mirror I learned my brain is stronger than my arms and I lacked the strength to remove everything much less get it all back together, I'd live with the defrost setting because on a nearly 30 year old truck I'm not spending a lot of money on it and it drives, I'm happy for that much. It's not a daily driver. I had to have my husband remove the old part, because the vacuum tubes on it were really on there good and again my brawn is not as powerful as my brain, I knew what needed to be done, I just needed someone else's muscle to do it. So it got switched out and nothing changed...but this is a vacuum issue, it's not an immediate fix, you have to give it time to get cleared out and being to vacuum the way it is supposed to. So maybe in the 3rd trip out with the truck, I tried moving the vent flow around and behold it now comes out at the dash and not windshield unless I actually have it on defrost. So this part fixed my problem and for the price is was well worth it. ## Features - GM-recommended replacement part for your GM vehicle’s original factory component - Offering the quality, reliability, and durability of GM OE - Manufactured to GM OE specification for fit, form, and function - Country of Origin: China ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0016I0E42 | | Best Sellers Rank | #23,939 in Automotive ( See Top 100 in Automotive ) #3 in Automotive Replacement Emission Vacuum Tee Connectors | | Brand | GM GENUINE PARTS | | Brand Name | GM GENUINE PARTS | | Connector Type | Compression | | Customer Reviews | 4.7 out of 5 stars 533 Reviews | | Exterior Finish | Machined | | Global Trade Identification Number | 00707773122037 | | Included Components | Check Valve | | Inlet Connection Type | Compression | | Item Dimensions | 2.7 x 1.4 x 1 inches | | Item Type Name | Check Valve | | Item dimensions L x W x H | 2.7 x 1.4 x 1 inches | | Manufacturer | ACDelco | | Manufacturer Part Number | 15-50568 | | Manufacturer Warranty Description | 24 Month / Unlimited Mile Limited Warranty on parts sold on or after 04/01/18.

The gas releases heat, condensing into a high-pressure liquid. After cooling, the liquid passes over evaporator coils to cool the air as it is blown through the vents. **Q: What are the signs the system needs service?** A: Common indicators of an air conditioning system in need of service include warm and/or weak airflow through the vents, frequent on/off cycling of the system and a strange or musty odor. **Q: Is the puddle of water under my car a sign of AC problems?** A: Not necessarily. Condensation typically builds up on the AC evaporator and the water is drained at the bottom of the vehicle. That’s normal, but a larger puddle combined with reduced AC performance could indicate a problem. **Q: Does low refrigerant mean there’s a leak in the system?** A: In most cases the answer is yes. AC systems in older cars will experience refrigerant leakage over time, but a later-model vehicle that needs continual refrigerant recharging typically indicates a leak. **Q: Can a new cabin air filter improve AC performance?** A: Yes. A very dirty or clogged cabin air filter can reduce the airflow of the AC system, reducing its cooling efficiency and making the system work harder than normal. Periodic cabin filter replacements help the AC system keep its cool. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good price for good product. *by M***N on January 27, 2026* It works great at a nice price. ### ⭐⭐⭐⭐⭐ It fixed my problem, 1994 GMC Sonoma *by M***Y on January 1, 2023* For years I've dealt with my truck only having airflow at the defrost blowing on the windshield.
