im working on a 2006 gmc sierra w/5.3. the problem that im having is the i have to replace the high and low beam relay every month or two. what happens is they just stop working, and when they do i replace the fulted relay with a replacement one they work again and if i put the old one back in they dont work again. if anybody has any thoughts would be much appreciated so i can stop banging my head off this truck. if you need more info just ask thanks.

Buy better relays.

You need to figure out what part of the relay thats going out...is it the X1 and X2 terminals...or the actual contacts...that will tell you what is giving you the problem...the activation circuit or the lighting circuit.

they are gm delphi relays, but the thing that i dont know is it something that just takes that long to blow the relay or is it something that just happins every now and then.

chances are its an every now and than thing....like a short.

Relays are not slow blow...they are high current switches activated by a low current switch...the rating on most relays is around 30-75 amps...most are around the 75 area. Not a wire in the truck aside from the Battery leads, starter and charging system will handle 75 amps.

 

You need to figure oput what part of the relay is blowing....the switch part or the coil part...that will tell you where the problem is. if its the coil...its on the dimmer switch side...if its the relay contacts...than its on the headlight side.

      Trans Cooler Thermostat Valve Body Seals - 2022 10L80

      By Rick_ · Posted

      Does anyone know if the GM 85628205 and 85628208 are interchangeable?   The 85628205 is an assembly of the seals mated to a thin metal shim and the 85628208 appear to be just the rubber seals without being an assembly. The reason I am asking is that I'm installing a PPE Thermal Bypass Valve and it doesn't come with seals.

      Can anyone decode a VIN to determine if this truck has had emissions issues or a recall?

      By cherryred21duramax · Posted

      Thanks @newdude, guess I'll keep looking.  Test driving so many trucks that have obvious things broken, I'm thinking "if they couldn't even be bothered to fix the power seat," what else is broken".   Just drove a 2021 where the power seat motor was grinding/binding and wouldn't do anything but make a terrible sound.   An owner that puts dents on the bumper, doesn't fix a seat motor, and had spotty service intervals (along with missing major services) doesn't give me the best of confidence.   Amazed at the number of people that will finance a $60k+ truck, run it into the ground, then trade with a loan balance (every single one had "loan/lien reported" on the CARFAX at the last year of registration).

      Not true! I have been runing them since 2006 F250! suspension component that works as a sway bar, a traction bar, and a helper spring points directly to the RoadActive Suspension (RAS) kit. Works as a sway bar, a traction bar, and a helper spring.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Here's a starter kit:    CC Jensen, a Danish oil testing Concern gives us the following guidelines:   ISO 14/12/10 Very Clean Oil ISO 16/14/11 Clean Oil ISO 17/15/12 Lightly Contaminated ISO 19/17/14 New Oil ISO 22/20/17 Very Contaminated and not suitable for any service.   In addition CC Jensen gives a table showing how engine life is increased by cleaning up the oil. For example cleaning the oil from 19/17/14 to 13/11/8 will extend motor life by a factor of 6X.   But even cleaning it two “Life Extension Classes” will double motor life. So perhaps giving those classes would be useful:   21/19/16 20/18/15 19/17/14 18/16/13 17/15/12 16/14/11 15/13/10 14/12/9 13/11/8   *************************************   https://testoil.com/program-management/setting-iso-cleanliness-targets/   Third paragraph from the bottom will give a starting point.    Your next question should be, okay 10um at what Beta ratio and the answer is in the graph Beta 75.   Then the next question is what is your chosen filters profile? (Purolator PL series below) The red dot is Beta 75. This was the information I obtained from MANN a few years ago. So the best filters, Purolator One, AMSOIL EA, FRAM Ultra, Royal Purple, Bosch Premium should get a doubling engine life over filters like Purolator L, any service filter from any quick lube, WIX, NAPA, STP, Mobil 1, Purolator BOSS.    And as noted by CC Jensen a 2-5 micron @ Beta 200 bypass system has the capability of a six fold improvement. AMSOIL has such a system as does Donaldson.       Now having said all that testing is the touchstone. Test the oil NEW and test it with your chosen filter. Then test over milage. Do the work, get the result. But understand this in NOT absolute BECAUSE this is one factor in isolation.   Example:    A valve spring supplier can state that with cam X and a valve train of Y grams the valves will not float to 7K rpm. is that true if the builder choose a system 20 grams over limit? Common sense must be used and limits understood.

      This doesn't look like a GM truck. Not needed on a HD truck
