Problem Solved, Not OVP or KILMA
Thanks for your reply,
The vehicle's A/C, Speedometer, and cruise control + the check engine light + Check Engine electronics message came on all at once, also retreived all codes P1335, P0505 (Idle Speed Control), and P0134 (O2 sensor), but the vehicle's engine ran perfectly. So I took the Vehicle to the dealer, and their estimate was for $2,800 the fix the following Items: Replave broken A/C hose. A/C dryer. Replace instrument cluster. Replace Alternator. Replace Battery Engine belt. Ofcourse I did not leave the vehicle at the dealer for them to repair it. As it turns out and after 4 weeks of research and testing electric components, I decided an hour ago to remove the instrument cluster due to the tachometer was not working and to my surprise once I disconected the Cluster from the vehicle(1996 E320) the A/C started working perfectly. It seems that the A/C module uses the tachometer as a reference so it knows that the engine is running, like the KILMA relay. I would not be surprised if the rest of the problems and codes go away after I have the instrument cluster repaired. Perhaps someone out there needs this information. Pass it along Where is this base module that you are refering to?? Thanks in advance Norman |
