Yo, I totally feel u on the rain soaking the door panels, it’s honestly the worst in these big vans! if you’re looking for the absolute best bang for your buck without paying the premium brand tax, I’d seriously look into Goodyear Shatterproof In-Channel Window Deflectors. I’ve done a bunch of market research looking for something that fits the Savana’s massive doors perfectly, and these have a really clean, low profile. They’re usually around $55 to $60 online, which is a total steal compared to some other options out there. Plus, they’re shatterproof so you don’t have to worry about them snapping if a branch hits 'em while you're out camping, right??

I was worried about the window motor too, but if you just leave the windows up for like 48 hours after installing, the seals stretch out and it’s basically fine. If you’re REALLY trying to save cash, Stampede 6046-2 Tape-On Wind Deflectors are another solid budget option, usually under $50. But yeah, in-channel is highkey better for that highway noise. gl with the van! 👍

Ok so i feel u on this one... i've been driving these big GM vans for like 15 years now and honestly, i've tried basically every style out there. For your Savana, i think the in-channel ones are way better for reducing that highway wind noise, but i'm not 100% sure if they wont mess with the window motor over the long haul. IIRC, some guys had issues with the window sensor thinking there's an obstruction, but it usually settles in after a few days. In my experience, they definitely look way cleaner and dont mess with the paint.

If youre worried about scratching the glass, i mean, it can happen if grit gets trapped, but its usually not a big deal if you keep 'em clean. But yeah, the tape-on ones? Honestly, i've seen way too many of those fly off on the highway cuz the adhesive just gives up after a couple hot summers. If you go that route, you gotta prep the surface perfectly or they wont stay.

For a "bang for your buck" option, i think EGR is actually a really solid choice. I've heard they fit the Savana frame a bit tighter than the cheaper generic stuff. I personally went with WeatherTech on my last van and the wind buffeting was LITERALLY cut in half. Its a total game changer for long trips and camping in the rain. So yeah, maybe check those out. gl!

+1! Safety-wise, I'm reallyyy satisfied with AVS Ventvisor In-Channel Window Deflectors 191414 over tape-ons:
- In-channel: No adhesive failure risk
- Tape-on: Better motor clearance
Highley recommend in-channel for ur highway stability tho!

100% agree

Similar situation here - I went through this exact same dilemma last year when I was prepping my Savana for a long trip. Honestly, over the years I've tried basically every brand, and I've become pretty cautious about the in-channel ones. I actually started with the WeatherTech Side Window Deflectors 80313 because of that clean look everyone talks about. They do look sleek, but on these GM van seals, I had a lot of trouble with the window motor sensor. The window would hit the deflector and just roll right back down... super annoying when you're trying to close it while driving!

Since I'm all about value and not breaking things, I ended up switching to the AVS Ventvisor Outside Mount Window Deflectors 2pc 92141. I was worried about them looking "cheap" or flying off, but honestly, if you prep the door frame with enough alcohol, that 3M tape is basically permanent. Plus, no motor strain.

If you want a middle ground, I've seen guys use the EGR Slimline Window Deflectors 573291 which are tape-on but have a much thinner profile. In my experience, the wind buffeting is definitely better with the in-channel ones, but the peace of mind of not burning out a motor on a 10-year-old van is worth the slightly bulkier look of the tape-ons. Just make sure you dont rush the install! gl!

I definitely agree with the points about the window sensors being a pain. Ive been running these GM vans for over a decade and seen plenty of window motors get tired early because of that extra friction in the channel stuff. If youre looking for the long-term safe play, dont sleep on the high-quality tape-on versions. They dont mess with your seals or glass at all, which is a big deal if you plan on keeping the van for a long time.

• Tip 1: If you go tape-on, use a heat gun or hair dryer to warm up the adhesive and the door frame before sticking them. It makes the bond basically permanent.
• Tip 2: To avoid that gap issue and get a better fit, look into Lund Ventvisor Elite Window Deflectors. They use a thicker material that holds its shape way better in high heat so they dont warp or whistle over time. Tbh the prep work is more important than the brand. If you scrub the area with alcohol first and use an adhesion promoter, they wont go anywhere even in a heavy storm. Just gotta take your time with the install and it pays off.
