There is a shop in Sadar RWP area as they specializes in central locking and power windows. I have installed power windows on my Rolla from them for around 25000. They have different packages like 9000, 15000, 18000 and 25000 ones. I went for the best as they offered everything original and grip to grip fittings in this.
Only thing I made sure was that I worked with him closely and got the power relay installed in main fusebox and made the connections using sleeves and heat gun.
Regarding the fusebox stuff, I had to call my electrician and ask him to open the fusebox (One in Engine Area) for me after buying the original grips(relay). I had to break the grip and take out the individual wires with its clips and reinserted the same in the fusebox. Then made the connection using sleeves and only wire which came out from the fusebox was the load wire which was further connected with the load wire (which powers all the windows) also, I bought 30 Amperes small fuse from the scrapyard and screwed this new small fusebox within the dash board and connection was completed. In-case of short circuiting so this fuse will be the first to go off.
No doubt, they know their work but once it comes to providing power they just tend to take it from a wrong wire. Job above was the extra work which my local electrician did and only reason he was called because he was good at opening the fuseboxes.
I don?t remember the name of the shop but its located close to Waseem autos.
P.S: i told them to come and do the entire work in my house and they did without any extra price.
