    Disable Daylight Running Lights (DRL)

    This will work as well, but note that fuse #15 is not a dedicated fuse for DRL. Removing is will also disable other functionality. For me it was most notably the dash lights. The mod described here not much harder or time consuming than pulling fuse 15.

    Disable Daylight Running Lights (DRL)

    I did just run across this on another forum: Posted on Diesel Place .com by go-dwr: Here is some info I got off another site for the resistor method I used. I have read several posts asking for information on how to disable the twilight (auto on) feature on the headlights of 99 FSCs. I...

    Disable Daylight Running Lights (DRL)

    I am pretty sure this will do it. This is the path that allows the system to turn on the lights via the DRL relay. I have heard that pulling the fuse works for some vehicles, although I don't feel it is isolated enough. GM/Chevy did not make it easy to disable the DRL feature due it being...

    Disable Daylight Running Lights (DRL)

    Can you explain to me what the twilight function is? The shop manual I have is very specific to a 1998 Tahoe, but if this feature was available in 98 I might be able to verify it affect.

    Disable Daylight Running Lights (DRL)

    This could very well apply to any GM vehicle using the same DRL Module 42767. I have messed with this problem for a while. Everyone has there method, and I found most of them are stop gap measures that really cause other issues. If you pull the DRL relay then other intrument features...

    Fan shroud for electric fans

    Yes on the seal. I designed it so that the fans would produce optimum flow through the radiator. I should have the first one made in about a week and I will post pics of it in the raw. I am going to weld up the seams just to keep it tight. It has an open hem on the botton to hook on a...

    Fan shroud for electric fans

    My measurements show 32.8. What are you measuring off of? This is on a 98 tahoe with an over sized radiator. I am going to have a single one made and install it in my truck. It will take about 1-2 weeks. I will post picks when I get it, and as I install it. I can not seem to get a good...

    Fan shroud for electric fans

    To all who are interested. I have designed a fan shroud that will hold 1 or 2 fans for my 98 tahoe. The shroud will cover the entire rear of the radiator to maximize the airflow of the fans. They will come blank meaning you cut the size/position of the hole(s) for your fan(s). I have a guy...

    lower ball joint on a 4x4...welded in?

    I have a 98 and replaced upper and lower ball joints. No welds. The lowers can be pressed out with a screw type joint press. The only way I could get them back in was to cut a metal pipe that rested on the outside of the joint lip and pound them in with a 4lb sledge. I did not remove the...

    Heater AC Control

    I have found that it is quite easy to knock the connector loose when messing with anything in that area. On a 98 there are three connectors, the main one will be on the right side (facing the control panel). If it does not have contact, it will not work.

    Heater AC Control

    You probably checked this already, but have you gone through the fuses.

    Heater AC Control

    Will the heater activate? If the compressor is dead you will get no cold air, but the blower should still blow. If the pressures are off in the system the compressor will not turn on. Have you checked the system pressures? I think running it should something like 250 high to 60ish low.

    AC Blower Speed

    Some interesting info on this. I have a 98 4door and decided to replace the evap. When I got the old one out the inlet side was not in great shape, but what pissed me off was the other side. Some genius decided to spec four layers of aluminum screen as some sort of diffusion filter on the...

    1998 HOE : AC Evaporator change

    In the process of this now. The dash does have to come out. Two tricks: 1. Follow the metal support rail on the lower dash, and unbolt that. 2. The 4 bolts that hold the internal steering column must come off, and the column pulled free. You can let the steering wheel rest on the seat...

    1998 HOE : AC Evaporator change

    This is what I am thinking, however, my father in law who is a mechanic for fedex says he found info that it can come out through the firewall. I have not had a chance to look yet; still at work. The job was estimated to be over $1K, so I am thinking the dash coming out is a major PIA.
