    Engine cranks, but only starts after letting off key? - I'm perplexed

    Hello all - thank you for your feedback so far. I think it's helping to narrow it down. I kept the suburban overnight at my house to see how it behaved this morning when cold. Went out and it started like normal. Fired while cranking and didn't have to let off the key. Drove it back to the...

    Engine cranks, but only starts after letting off key? - I'm perplexed

    Hello all! I'm perplexed...I think the repair shop is getting there too. I recently had my suburban break down on the weekend shortly after leaving the house. The engine bucked a couple times before briefly stumbling and dying. Coasted into a parking lot and had it towed to a local shop. It...

    Module under Radio

    I think you’re spot on. Googled the info and the images look just like that module I saw below the radio. That makes me feel better that I can rule that out as the culprit. The local shop found multiple vacuum leaks around the throttle body and intake manifold. They’re convinced those repairs...

    Module under Radio

    Hello all On my 91 suburban - Does any by chance know what the white-ish module mounted on the lower dash, underneath the radio is? I unfortunately don’t have a picture of mine, but I noticed it when removing/reinstalling my factory radio this past week. I reinstalled the radio Thursday...

    91 Burban Radio Restoration - Static Gone!

    Hello all! Awhile back I had posted about speaker ohm, thinking the static/crackling I was getting on the right channels was a speaker issue. See thread here: https://www.gmsquarebody.com/threads/91-suburban-rear-speaker-which-ohm.40512/#post-856426 Well....I was doing a little more...

    Front Fender Well Inspection Covers?

    Hello all - on my 91 suburban, the front fender wells have what looks like an inspection cover on the rear side (see pics below) held in by three bolts. Not sure what the purpose of these covers were, but mine have rusted through over time and would like to replace them before the rust cancer...

    Best deal on leaf springs?

    I bought my replacement rear leafs from General Spring KC. The best deal I could find on rear leafs. Much less than LMC. Shipping was quick and staff was friendly in answering my questions on the phone. They did develop an awful creaking noise shortly after install and cycling the...

    91 Suburban Rear Speaker - Which Ohm?

    Well - gave it some contact cleaner and worked the knobs. Seems like I have an issue with the radio itself as it's still making sporadic static/popping noise on the right side. More so in the back right speaker than the front right. I tried pulling the entire radio out, but it was not...

    Rear AC Blower Motor/Fan

    Well after a little more researching, I found an AutoZone hub not too far away that had one on the shelf for $35. Also had the factory plug/connections surprisingly, rather than bare pigtails. Tech Tip - triple check the orientation of your fan cages. After installing the new motor and...

    Rear AC Blower Motor/Fan

    Happy Saturday everyone! My rear AC fan was rubbing the plastic housing. Took it apart to inspect and it looked like the fan motor shaft had some side to side play in it. One side had a push nut/clip but the other side did not. Took it out and installed a push nut/clip on the side that was...

    91 Suburban Rear Speaker - Which Ohm?

    Picked up some contact cleaner last night. Going to give it a shot this weekend and see if there is a change. That's what made me hook up the meter to measure the ohms across the positive/negative terminals. I didn't want to further damage the radio by hooking up a speaker with the wrong ohm...

    91 Suburban Rear Speaker - Which Ohm?

    Hmmm that could be possible considering the static is on the same side/channel, and adjusting the left/right knob did help some. Adjusting the back/front didn't appear to affect it as much. It's only happened once (last night) and what was odd is that increasing/decreasing volume using the...

    91 Suburban Rear Speaker - Which Ohm?

    I've been getting some static on the right channel (front and rear) of my suburban recently. Not quite sure if it's the original radio head unit causing the issue or original speakers finally biting the dust. Pulled one of the rear speakers out to see if it listed what ohm it was rated for...

    AC Compressor Change - Accumulator/Orifice Tube Criticality

    Thank you PeteJr! It's a fun vehicle to tinker with, despite the cussing/busted knuckles during tinkering haha!

    Say no to Cracks

    FYI - if you have factory oil cooler lines, it really puts a bind/pressure on the lines if you don't modify the bottom edge of the main brace. I test fitted it a couple times and ended up notching the bottom to allow the lines to maintain their original position. I trimmed it and have about...

    USA1 Industries

    I’m fortunate in that I don’t live far from them. I went once because it was almost impossible to reach them by phone and I was driving right by their showroom. The showroom had quite a bit on display, and surprisingly there was staff inside and they had phones on their desk! Lol They were...

    AC Compressor Change - Accumulator/Orifice Tube Criticality

    Doesn't appear to freeze so I'm leaning towards that it's operating correctly. It's a dual AC system with rear AC. Agreed, the desiccate bags are my main concern, especially being original. That's why I asked them to replace it when replacing the compressor. Good point on the orifice tube...

    Say no to Cracks

    I recently purchased the ORD box brace as well. When I held the main brace up to see how everything lines up, it looks like the hoses for the oil cooler will interfere slightly on the bottom of the brace edge. The ORD installation instructions note this, but their website makes no mention of...

    Steering rebuild question

    I just replaced the drag links, tie rod ends, and both adjusting sleeves on my Suburban. My drag links/sleeve was 7/8" diameter and the tie rods/sleeves were 1" diameter. Keep in mind this was on a 91 Suburban 4WD so I'm not if that would apply to your K15. I spent countless hours researching...

    AC Compressor Change - Accumulator/Orifice Tube Criticality

    Hello All! New kid on the block, but not new to the 91 Suburban in the garage. I am the fortunate new-ish owner of the Suburban my parents bought new in 91. So many family trip memories that I had to keep it in the family. Being stored indoors it's whole life, it has been preserved well...

    R4 to Sanden whith stock ac lines(for serpantine)

    Thank you! The 91 Burb I have was bought new in 91 by my parents, but over the last 1.5 years I've been trying to preserve it as much as I can. However, the NC summers have pushed me to consider deviating from original when it comes to AC. The Sanden route is very appealing for creature...

    R4 to Sanden whith stock ac lines(for serpantine)

    Thank you both. That's much more inexpensive than some of the Vintage Air mounts I was combing through (although those were more geared towards a LS crate engine). I wish I had a way to cut/fabricate the mounts with the drawings, but unfortunately don't have the tools to do so. One follow up...
