I replaced the distributor in my '95 2 door Tahoe and it ran like pure crap afterwards. I did not know there was a brown wire w black stripe under the glove box that has to be unplugged first or the ECM will advance the time 20 degrees. Thank God for KZitem videos. Mine was way off! My harmonic balancer was also covered in crud and I couldn't see my timing mark. With the engine running I crawled under it with a steel bristle brush (for cleaning my charcoal grill. Ha!) and held it against the balancer as it spun and it came spotlessly clean in seconds so I could see the timing mark. After setting time correctly it ran like a champ! I made a celebratory trip to the beer store afterwards.

that tapping under the dash is your "blend door actuator" located behind the glove box, it acts as a fuse also and can fry components in your dash if not replaced. It operates a door for your heat/ac control switch to change from blowing air on defrost/floor/vents

thorjames26 look up chevrolet blend door actuator, for the one on the passenger side normally you would remove the glove box completley to get behind it, as well as most of the duct work under the dash for a part the size of a hockey puck. It sucks but while you have it all apart you might as well replace the under dash light bulbs, i bear hugged the dash holding a microrachet in one hand and finger on the socket with the other, all for 1 screw. Sounds horrible and it is. I would recomend a weekend of pulling the dash apart. Reason is when that part doesnt work it sometimes acts like a fuse and short circuits the dash, frying your radio.

Also, if your brown wire with a black stripe is not in the engine compartment, then check right behind the glove compartment. I have a 1994 Chevy k1500 5.7L and they moved it on that year to behind the glove compartment inside the truck - right next to the computer. The glove compartment comes out without unscrewing anything, by the way. It's completely tool-less. It could also be closer to the floor by the carpet and blower motor under the glove compartment in some trucks.

That ticking is your "blend door actuator." It's an electric motor that opens and closes doors in your dash to direct the heater and A/C air. Sounds like the one that recycles the A/C air from inside the cab when "Max" A/C is turned on. It's right behind the blower motor in the passenger foot-well, where the firewall meets the cab floor. When you turn the truck on and off it opens and closes - and since it's weak and failing - you get the tick tick tick every time it tries to open and close. $20-$30 part. Installation is a pain in the ass. *You do not need to take the glove compartment out, by the way.*

there is actually a set of breakers that are under the dash you need to locate the one that is ticking and replace it. remove the glove box and cycle the truck long enough to cause the tick and out your finger on the three breakers and locate which one is bad they are expensive.

I've got a 1993 and I could hear the thumping noise in the background yall were talking about on the truck you were working on and mine does the same thing. It's a loud thumping noise coming from somewhere around the heater box/blower motor. I hear the noise each time the key is turned on and each time its turned off. My 1993 never made that noise until the a/c and heater control display went out. I was wondering if y'all were ever able to address the issue and figure out what to do to fix it. Hope to hear back from you. Thanks Jared

The ticking time bomb is possibly the actuator for the air diverter behind the blower motor, sounds like the diverter door is probably stuck. Try changing your climate control temperature setting back and forth from hot to cold. You will know real quick if working right. GM trucks are known all to well for this problem

No you can't check for TDC with the timing light..take your distributor cap off..Now pull out your number one plug which is the first plug on the drivers side in the front of the block..now turn over your engine by hand with the crankshaft bolt..turn it clockwise until the line on the pulley lines up with 0 or the Arrow on your timing chain cover..stick a straw into the spark plug hole if it doesn't go all the way down your piston is at the top..now look at where your rotor is pointing..if it's pointing towards the firewall you are not at the compression stroke or the distributor is in 180 off..if it's pointed towards the front somewhat you should be at TDC..if you have a round distributor cap the number one plug goes where the Rotor is pointing..mark the distributor where it's pointing and when you put the cap back on you'll know which plug wire connection is above the mark...let me know if that helped you out

+sal oliva, +Andrew Sybert you have a couple reasons it could be doing that. not knowing everything you have done/ tried here is a basic list of what I have found as "common" fixes 1. fuel filter. if it's pretty old replace it. 2. cap/rotor/wires/plugs---not necessarily replace but check to make sure they aren't corroded and still in good service life. usually everyone starts with those. but here's a little farther in TPS (throttle position sensor) IAC (idle air control) valve. it controls idle and fuel mixture. its a 5 minute change. I've had one bad and it kills MPG, will stall out on decel, stall out taking off, no low end power and less power through the range. mines a manual so I could usually keep it from dying. fuel pressure regulator, especially if its running rich and flooding out. engine temp sensor. the 2 wire one by the thermostat. the single wire is for your dash. EGR not functioning properly- plugged or bad valve. vacuum leak-which I hate looking for, but usually an easy fix. but hopefully by now you have them all fixed and running strong
